Installed it on two sites and did some small tasks (meta - alt - etc). It worked well.

I was in the middle of a cleanup for a new client so I installed on the staging site. Ran a "remove duplicate H1s" while I was logged into the live site (but no plugin installed). I did mess up and put the live site URL in CR forgetting to put the staging url. After I ran the task, I thought it was great... until I saw it removed 35 pages on the live site. Installed yesterday's backup. No avail. Installed last week's backup. Same issue. I don't know how it did what it did (htaccess?), but I had to recover those pages, and rebuild 9 of them from scratch (custom posts).

I wanted to leave this for support instead of in public, but the dashboard has no link to do so. No support ticketing, no chat.

I know I had a hand in putting in the wrong URL, but I'm guessing it should not have removed pages that could not be recovered. And it should not have done so via the staging site to live site. What a weird way to remove duplicate H1s.

This is a promising plugin! But I do want others to be aware that you can make a mess if not careful.
