Questions answered
WordPress plugin and theme FAQs
Answers about installing, updating, disabling and testing extensions without losing your route back to a working site.
How do I install a WordPress plugin safely?
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.
How can I find a WordPress plugin conflict?
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.
Can I deactivate a plugin without wp-admin?
Use hosting File Manager to rename the specific plugin folder after confirming its identity and preserving a backup. Follow the deactivation guide to visit the Plugins screen, confirm its state and restore the folder name without reintroducing the fault.
What should I do before updating WordPress plugins?
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.
Can I roll back a WordPress plugin update?
Check the developer's supported recovery method first. Older files can be incompatible with database changes made by the update. The rollback guide explains how to choose between a trusted release package and a coordinated restore while preserving newer data.
Is deleting a plugin the same as deactivating it?
No. Deactivation leaves the plugin installed, and its own deactivation routine determines any accompanying data changes. Deletion removes its files and can run an uninstall routine. Follow the plugin removal guide before deleting a tool that stores forms, orders or other records.
How do I check whether a plugin is compatible?
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.
Does every theme customisation need a child theme?
A child theme helps keep custom template files and code separate from a parent theme's updates. Normal editor settings do not automatically require one. If design controls fail to load, first check the Customizer guide, including the different editing tools used by block themes.
Can I switch a broken WordPress theme through SFTP?
File access can help recover the Themes screen, but renaming the active folder does not guarantee a working fallback. Follow the theme recovery guide to prepare a compatible installed theme, record the original folder name and verify the design after activation.
When should a plugin or theme problem go to a developer?
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.
