WordPress sites need regular maintenance to stay secure, stable, and compatible with plugins and themes.
In Antihost, you can manage your WordPress site through WordPress admin and, depending on your plan and available features, through the Antihost panel.
Good to know
Updates are important, but they can also break a site if plugins, themes, or custom code are not compatible. For important sites, update safely: backup first, test when possible, then apply changes.
Why WordPress updates matter
Updates keep your site secure and stable
WordPress updates may include security fixes, bug fixes, compatibility improvements, and new features.
Keeping WordPress updated helps reduce the risk of:
- security vulnerabilities;
- plugin conflicts;
- theme compatibility issues;
- broken functionality;
- outdated PHP or WordPress behavior.
Updates can affect how your site works
Not every update is risk-free.
An update can affect:
- page layout;
- forms;
- checkout;
- custom code;
- plugin settings;
- theme templates;
- admin dashboard behavior.
Important
Do not treat updates as a purely cosmetic task. On a production WordPress site, updates can affect real users, leads, orders, or business-critical pages.
How to update WordPress
Open WordPress admin
To update WordPress, log in to your WordPress admin dashboard.
You can usually find WordPress updates in the dashboard under the updates section.
There you may see available updates for:
- WordPress core;
- plugins;
- themes;
- translations.
Check what update is available
Before updating, check what type of update is shown.
A minor WordPress update may include security or maintenance fixes.
A major WordPress update may introduce larger changes and may require more careful testing.
Recommended
For business-critical sites, do not apply major WordPress updates directly on live without checking backups and, if available, testing on staging first.
Run the update
Start the WordPress update from the WordPress admin dashboard.
Wait until the process is complete before closing the page or starting another update.
After the update, open the site in a browser and check that the main pages still work.
Important
Do not refresh, close the tab, or start multiple updates at the same time while WordPress is updating.
When to create a backup before updating
Create a backup before risky updates
Create a backup before updates that can affect site behavior.
You should create a backup before:
- major WordPress core updates;
- bulk plugin updates;
- theme updates;
- WooCommerce updates;
- page builder updates;
- security plugin updates;
- caching plugin updates;
- custom plugin updates;
- updates on sites with payments, forms, bookings, memberships, or user accounts.
Simple rule
If the update can break the site or affect business data, create a backup first.
Create a backup before updating live sites
For live production sites, especially business-critical ones, backup before applying updates.
This gives you a restore point if something goes wrong.
Important
If your site receives orders, leads, form submissions, or user registrations, check recent activity before restoring an older backup. Restore may replace data created after the backup.
How to manage auto-updates
What auto-updates do
Auto-updates allow WordPress, plugins, or themes to update automatically when a new version becomes available.
This can reduce manual maintenance, but it can also introduce risk if an update breaks compatibility.
When auto-updates are useful
Auto-updates may be useful for:
- simple websites;
- low-risk plugins;
- security patches;
- small maintenance updates;
- sites without complex custom logic.
When to avoid auto-updates
Avoid enabling auto-updates for critical or complex parts of the site without testing.
Be careful with auto-updates for:
- WooCommerce;
- payment plugins;
- booking plugins;
- membership plugins;
- LMS plugins;
- page builders;
- custom plugins;
- caching or performance plugins;
- active theme on a custom-designed site.
Recommended
Use auto-updates carefully. For business-critical websites, controlled manual updates with backups and staging are usually safer.
How to manage plugins
How to activate a plugin
To activate a plugin, open WordPress admin and go to the plugins section.
Find the plugin you want to use and select the activation option.
After activation, check whether the plugin adds new settings, pages, or admin notices.
Good to know
Some plugins require additional configuration after activation. Activating a plugin does not always mean it is fully set up.
How to deactivate a plugin
To deactivate a plugin, open the plugins section in WordPress admin and select the deactivation option.
Use this when you want to temporarily stop a plugin from running.
Deactivation may be useful when:
- troubleshooting a conflict;
- checking site performance;
- replacing one plugin with another;
- testing whether a plugin causes an issue.
Important
Deactivating some plugins can affect site functionality. Be careful with plugins used for checkout, forms, security, SEO, caching, memberships, or custom features.
How to update plugins
Plugin updates are usually available in the WordPress updates section or directly in the plugins list.
Before updating plugins, check:
- which plugins have updates;
- whether the update is major or minor;
- whether the plugin is critical for the site;
- whether a backup exists;
- whether staging should be used first.
For multiple updates, it is safer to update plugins one by one or in small groups.
Recommended
Avoid updating many critical plugins at once on a live site. If something breaks, it becomes harder to identify which update caused the issue.
How to manage themes
What a theme controls
A WordPress theme controls the visual structure and layout of your site.
It can affect:
- page templates;
- header and footer;
- typography;
- colors;
- layout;
- blog design;
- WooCommerce templates;
- responsive behavior;
- site editor settings.
How to install or change a theme
You can manage themes from WordPress admin.
Before changing the active theme, create a backup and, if available, test the change on staging.
Changing a theme can significantly affect how the site looks and works.
Important
Do not switch themes directly on a live production site unless you are sure the new theme is configured and tested.
How to update a theme
Theme updates may include security fixes, compatibility fixes, or design changes.
Before updating a theme, check whether the site uses:
- a child theme;
- custom theme files;
- custom CSS;
- custom templates;
- page builder templates;
- WooCommerce templates.
Important
If your site has custom theme changes, a theme update may overwrite or affect them. Test first if the site depends on custom design or templates.
What to check after updates
Check the public site
After updating WordPress, plugins, or themes, open the site as a visitor.
Check:
- homepage;
- main navigation;
- important pages;
- forms;
- buttons;
- images;
- mobile layout;
- footer;
- login/account pages, if used.
Check business-critical flows
If your site depends on conversions or transactions, test the most important flows.
For example:
- submit a contact form;
- test newsletter signup;
- add a product to cart;
- check checkout pages;
- check booking forms;
- log in as a user;
- open landing pages used in paid traffic.
Recommended
Test both desktop and mobile after updates. Some issues only appear on mobile layouts.
What to do if the site breaks after an update
Do not keep making random changes
If the site breaks after an update, avoid changing multiple things at once.
Random fixes can make the issue harder to diagnose.
First, identify what changed:
- WordPress core update;
- plugin update;
- theme update;
- multiple updates at once;
- auto-update;
- custom code change.
Simple rule
If the site breaks, stop and identify the last change before applying more fixes.
Check if you can access WordPress admin
If WordPress admin still works, check:
- active plugins;
- recently updated plugins;
- active theme;
- error messages;
- site health notices;
- plugin conflict warnings.
If the issue started after a plugin update, try deactivating that plugin if it is safe to do so.
Important
Be careful when deactivating business-critical plugins such as payment, checkout, membership, booking, or form plugins.
Restore from backup if needed
If the site is broken and the issue cannot be fixed quickly, restore from a backup created before the update.
Before restoring, check whether the site received new data after the backup was created.
This is especially important for:
- WooCommerce orders;
- form submissions;
- user registrations;
- bookings;
- memberships;
- content updates.
Critical note
Restoring an older backup may remove data created after that backup. Check recent activity before restoring a live site.
Use staging for troubleshooting
If staging is available, use it to reproduce and fix the issue safely.
You can test plugin/theme changes on staging before applying them again to live.
Recommended
Use staging for debugging whenever the live site is business-critical or receives active traffic.
When to contact support
Contact support if the issue affects the live site
Contact Antihost support if:
- the site is down after an update;
- WordPress admin is not accessible;
- restore does not work;
- the site shows a server error;
- SSL/domain access changed after update;
- you are not sure whether to restore a backup;
- a plugin/theme update broke a business-critical flow;
- you need help understanding whether the issue is WordPress-level or hosting-level.
What to include in your support request
When contacting support, include:
- your domain name;
- your WordPress hosting plan;
- what was updated;
- when the update happened;
- whether it was manual or automatic;
- whether the issue affects live or staging;
- whether a backup exists before the update;
- the error message or screenshot;
- whether the site uses WooCommerce, forms, bookings, memberships, or custom code.
Why this matters
Update issues can come from WordPress core, plugins, themes, custom code, or hosting configuration. These details help support identify the correct layer faster.
Summary
Update carefully, especially on production sites
WordPress updates, plugin updates, and theme updates are part of normal site maintenance.
For simple sites, updates may be straightforward. For business-critical sites, use a safer workflow:
- Create a backup.
- Test on staging if available.
- Update WordPress, plugins, or themes.
- Check the public site.
- Test critical flows.
- Restore or contact support if something breaks.
