If you know what you are doing, this plugin is priceless. For some features, there are no alternatives at all.

What other people are saying this plugin does, it did to me. As so many people describe, I used it once, and when I exited troubleshooting mode, ALL MY PLUGINS STAYED DEACTIVATED. I now have to restore my site from backup! NOT COOL!

DO NOT use this on any of your Live and important sites

A disaster! The plugin deactivated and deleted most of my plugins. Impossible to restore without restoring the site from a backup. I've been an experienced woocommerce seller for many years and I haven't been able to solve the problem created by this plugin without restoring the backup from my host.

I didn't try it because of negative reviews and untested. If the problem is 53 out of 100 negative, that's more than half. Why is it still being offered as a means of help and health of your website???

I needed to use this plugin to troubleshoot a plugin conflict on my website, it ended up screwing my website. I had to restore from backup.

Bei mir hat dieses Plugin perfekt funktioniert, danke!!!

Zur Funktionsweise: Sobald dieses Plugin installiert und aktiviert ist, werden alle anderen Plugins deaktiviert. Nun kann man nacheinander jedes der schon zuvor vorhandenen Plugins aktivieren und jeweils prüfen, ob das Problem soeben behoben wurde.

Bei meiner Webseite hatte < MainWP Child > das Problem verursacht.

I really like it. It useful to figure out any issue by using troubleshoot mode.

Thank to the author of the plugin.

Too bad I didn't read the warnings here before I installed.

Installed, activated, and selected Troubleshooting. Boom! Site is gone. Error 500 with nothing in the logs.

Deleting the plugin via ftp didn't help so now I have to get it restored from backup.

Pathetic.

As others have said, troubleshooting mode breaks your website. You will abruptly lose access to the dashboard, can't login, and the website itself won't load for users. The fix?

Go into your web directory through FTP and delete the plugin from your wp-content folder. When I did this I was able to reload the dashboard. Oddly, even without the plugin, I was prompted to disable troubleshooting mode, which I did, and then everything was restored.

Update: After deleting the plugin through FTP, the ability to "troubleshoot" from the plugins page was still there — and causes a "critical error". Thankfully, the back button took me back. There's also a weird "must use" plugin artifact. By re-installing Health Check (but NOT activating it) and then deleting it again, these artifacts disappear. What a disaster of a plugin.
