Can’t use editor while plugin is active

One problem I keep running into… If I’m working on editing a theme or child theme in the editor, I have to disable the plugin every time I need to save a change.

If the plugin is active, it gives the error “Unable to communicate back with site to check for fatal errors, so the PHP change was reverted. You will need to upload your PHP file change by some other means, such as by using SFTP.” any time I click “Update File”.

So I have to constantly disable the plugin when modifying themes or child themes.
