Having the same problem, so I decided to bump the topic. This happened to an almost fresh install, the only things I did was change the front page to be the about page, added 2 admins (myself under my name and the co-founder) and installed a few themes. I can’t even access the admin panel in any way. If there is something wrong in my database, I would like to know what to fix.
We are using MySQL5 and I don’t know what version of WordPress I’m running for sure because I can’t log in to the site in any way and can’t find that information in the database, sorry.
