Good suggestion. I’m quite familiar with that troubleshooting method. I’ve used it many times. This was actually one of the first things I tried this morning (out of a long list of many items). Unfortunately, it didn’t make any difference. I got the error even with all plugins deactivated.

I actually cleared all cookies and cache on this machine. However, I haven’t tried logging in from another machine. Just tried it. Same error. I’m gonna upload a file, force-upgrade.php, that someone gave me in the OP FB group and try that.
I broke it again when I was installing bbPress. Turned out there was a conflict between the OptimizePress theme and bbPress. Long story short. I installed a different plugin and I now have the forums working. I re-ran force-upgrade.php yesterday and my login is working again. I think I can finally put this one to bed. Yeah!!!
Yes and no. bbPress itself didn’t cause the issue. It was a conflict between bbPress and the OptimizePress theme. bbPress seems to work fine with the OptimizePress plugin. I found out that this was a known issue in that several people had reported it. Unfortunately, OptimizePress (the company) has done nothing about the issue even though it was first reported at least two years ago. I don’t think bbPress caused the login errors. I think those occurred because something got jacked up in the WP database after uninstalling bbPress. Luckily, I found out about force-upgrade.php which worked great to clean up that issue.
I wound up using Simple:Press for the forums. That plugin seems to work fine with the OptimizePress theme. You can see the page at http://yourpathtoweightloss.com/forums/. There’s not much to see, though. I’ve got two forums in there but I haven’t turned off the security for the forums themselves so they won’t be visible. I turned off the security for the page itself so people in the OptimizePress Facebook forum could see how the page was rendering. It’s not perfect but I’m going with it for now so I can move on to other things.
one thing I have learned over time is that the fewer plugins you can use to get the usability you need on your site, the smoother things will run in the long run! the more plugins, the more chance of conflict down the road, during a routine upgrade.
Be sure you are taking full daily backups so that you can, in a worst case scenario, revert to the previous days snapshot and you only lose a day’s posting!
I agree. I have very few plugins installed on that site. I have a plugin that runs daily and weekly backups. The daily backups aren’t full (in that I’m not backing up the full site – maybe I should be). The weekly backups are full. In any case, I don’t think a plugin itself caused the login errors. I think those somehow got caused when I removed the bbPress plugin. No idea how. All I know is that after I removed bbPress, that’s when the trouble began.
