WordPress plugin tutorials, made safer.

Confirm the plugin is maintained, compatible with your WordPress and PHP versions, and obtained from a trusted source. Back up the site, install it on staging where practical, configure only the features you need and test key pages before live activation.

Reproduce the problem, review logs and recent changes, then deactivate likely plugins one at a time on staging. Retest the same action after each change so you can identify the conflicting combination rather than assuming the last visible error is the cause.

Yes. Rename its directory through SFTP or a hosting file manager, or deactivate it with WP-CLI. WordPress will treat the missing directory as inactive. Restore the original name only when you are ready to test it again.

Create a current backup, read the changelog, check compatibility and record the existing version. Test business-critical updates on staging, then verify forms, logins, checkout and scheduled tasks after updating the live site.

Often, but the previous plugin files may not match database changes made by the new version. Use a backup or trusted release package, check the plugin's rollback guidance and retest the affected feature before leaving the older version active.

No. Deactivation stops the plugin code from running while leaving its files and usually its settings in place. Deletion removes the plugin files, although database tables, options or uploaded data may remain unless the plugin provides a cleanup process.

Review its supported WordPress and PHP versions, recent updates, changelog and known issues. Compatibility labels are only a starting point, so test the plugin with your active theme and important extensions on staging.

A child theme keeps template and style changes separate from the parent theme, so normal parent updates do not overwrite them. It still needs testing because parent changes can affect inherited templates and hooks.

Yes. If another installed theme is available, renaming the active theme directory can prompt WordPress to fall back. Back up first and expect widgets, menus or template settings to need checking after the switch.

Get help when the fault affects checkout, data, security or the only live copy, or when it requires PHP changes rather than configuration. Keep the failing versions and logs available so the cause can be reproduced accurately.
