The plugin allows you to disable/enable plugins and/or activate a default theme for checking conflict between them only for your IP; other users won’t see any changes during the tests.
It is made for developers, techical support engineers, as well as for regular WordPress users. Sometimes, usually after updating your plugins, themes or WordPress installation, strange issues may appear and mess the things up. This plugin provides a really neat way to check the problem.
What I couldn't figure out yesterday in three hours, I figured out today in less than one hour with the help of this plugin. Very useful when pushing to a staging site for conflict testing isn't feasible.
After some cowboy coding, I was just spinning my wheels when I couldn't figure out which plugin was causing a conflict with Elementor on the main site of a multisite installation.
But, after finding this plugin I could 'quickly' isolate he offender on the site in question without deactivating all plugins (incl. network activated ones) and thereby affecting the entire multisite for all users!!
