From the developer

NSquared's own description of Plugin Detective, lightly tidied.

Plugin Detective helps you troubleshoot issues on your site quickly and easily to find the cause of a problem. Once the culprit is found, the problem plugin can be quickly deactivated. You can even fix your site when it has the white screen of death (fatal error). You’ll want to have Plugin Detective installed, so if your site crashes from a conflict or bad plugin update, you can get it back up and running quickly!

Plugin Detective is your best friend when you need to:
– Troubleshoot WordPress plugin conflicts
– Remove stuck .maintenance files
– Recover your site from fatal errors caused by plugins

We’ve all been there–something’s broken on your site. You’ve looked around the web for advice about what to do and have stumbled across the typical wisdom: deactivate all your plugins and then reactivate them one by one, checking your site for the problem after each reactivation.

Ugh.

Sure, it works. But who has time for that?

Find Plugin Conflicts with Detective Otto Bot

Detective Otto Bot walks you through solving your case one step at a time, all from one single screen.

  1. Open a case and tell Detective Otto where you’re seeing the problem. If your site requires any plugins to run correctly, tell Otto about those, too.
  2. Then, Otto will interrogate the suspects and track clues, checking in with you from time to time.
  3. All you need to do is answer “Yes, it’s fixed” or “No, it’s still broken” each time. Otto will do the rest and find the culprit in minutes.

Best of all – Plugin Detective can work even if you’re seeing the White Screen of Death on your site or if all you can see are PHP errors. Please have a look at the FAQ’s for how to access Plugin Detective and log into WordPress even if you can’t get to your login screen.

Once Otto has identified the culprit, you can quickly deactivate the troublesome plugin and go about your day.

Remove Stuck .Maintenance File or Scheduled Maintenance

Have you gotten stuck in maintenance mode on WordPress? The dreaded “Briefly unavailable for scheduled maintenance. Check back in a minute” message haunts you; the minute never ends!

With Plugin Detective installed you can quickly get out of these situations without the hassle of deleting files via your host or FTP. Just tack on this slug to the end of your website URL:

/wp-content/plugins/plugin-detective/troubleshoot/?restore=1

So that your URL looks like this:

https://yoursite.com/wp-content/plugins/plugin-detective/troubleshoot/?restore=1
