I finally got control of my blog sort of last night by trying the 2.1.1 upgrade. Then the news is delivered that it was hacked LOL. Upgraded to 2.1.2 and wah la – for about an hour! Error 500 again and again! It is hard to fix a problem when you can not access the dashboard.
I due to the problems since Monday had already set up some log files on my host server. They do not let you access much but I did manage to figure out how to log script errors saved. Woo hoo! A plug in was throwing errors like crazy! The Autometa plugin. So, disabled it and arrived without a 500 error page.
If you can not access your 2.1.2 WordPress site and are using this plug in you might try waiting for your open connections to close, log in while you can and disable it! Hopefully this is a final solution to this blogs problems.
More later.
