We always recommend running Plugin Detective on a staging site and completing the entire troubleshooting process. If you stop in the middle of the troubleshooting process, the site is in an unsafe state. We try to communicate this in the plugin but will work on making that more clear.
We also responded to a support request within minutes to offer help but didn’t receive a response ahead of this review ??
