With “Deactivate Plugins Per Page” you can easily disable plugins on certain WordPress pages (or on all except a selected page).
You can add deactivation rules for active plugins. For example for a contact form plugin, that you only use on the contact page, simply add a rule to deactivate it on all URI except on the contact page.
1. Deactivation Type
– Deactivate on selected URI
– Deactivate on all URI except selected
2. URI selection type
3. [Page] Select pages to extract URI from (it will update automatically if the page slug changes)
3. [Custom] Custom URI condition
– URI equals …
– URI does not equal …
– URI contains …
– URI does not contain …
– URI starts with …
– URI does not start with …
– URI ends with …
– URI does not end with …
4. Affected devices
Create groups of multiple plugins in order to add deactivation rules that affect them all.
Enable debug mode to see what is the URI and which plugins are active/inactive on the current page on the front-end. This will help you create rules and test current ones. A debug box will appear on the front-end if you are an administrator user.
There is an option (not enabled by default) that makes all rules with Custom URI selection to also affect the back-end. Some back-end pages will still not be affected in order to avoid problems, like the pages that control plugin activation, deactivation, updates, and installation.
Group plugins that work together
If you have a plugin that requires another plugin to be active in order to work, you need to add these plugins in a plugin group, and add deactivation rules to that group. Deactivating only one of these could lead to errors or the global deactivation of the other plugin.
Don’t deactivate plugins required by your theme
Some themes require certain plugins in order to work properly. If you deactivate these plugins you may experience problems.
Deactivation hooks will not run
When plugins are deactivated via my plugin, the actual deactivation function is not called, and the deactivation hooks will not run. Instead, to make it work per page, plugins are just dynamically removed from the list of active plugins before the page loads. This means that if a plugin has some actions that it performs when it is deactivated, these actions will not run when it is deactivated via my plugin.
For example, some plugins add code to your ”.htaccess” file when they are activated, and when they are deactivated, they remove it. In this case if you add a deactivation rule with my plugin to stop the plugin on a certain page, the ”.htaccess” code will still be there and work on that page, even though the plugin will not be active on it.
Don’t use this plugin to hide sensitive data
It is not made to work securely for that. It is mainly made for site speed optimization and it can also be used for debugging or solving plugin compatibility issues.
Backup your site
Deactivating plugins per page is not a natural thing for WordPress, and plugin and theme developers are not expecting that. It works great in most cases, but sometimes can lead to problems, to other plugins being deactivated or settings being changed. Always have a recent backup of your site and if you can, test your changes in a staging site.
These are the highest versions of WordPress and PHP where I have tested the plugin. They are not required, it will work with lower versions too. It could also work with higher versions, but it is not tested at this time on higher ones.
