Really Nice plugin
Really Nice plugin. I like it

The Plugin Works as What it's Saying
While testing multiple third-party addons on my site, I activated all the plugins at once to speed things up but it caused a fatal error, and I couldn’t figure out which plugin was responsible. Later, I discovered this plugin, and it really saved me by automatically deactivating the faulty one. Great work, super useful!
