It's so bad that I'm still digging out from the rubble. Right now my WordPress install is seriously borked and I don't know how to fix it. There are several plugins not working, my posts aren't automatically sending pingbacks (they are supposed to be).
If you want to see a visible sign of the problems, check out my homepage. The Morning Coffee post isn't supposed to be at the top of the page. I didn't make it a sticky nor change the date or time. It just won't move down like it is supposed to.
If anyone knows how to fix this (without reinstalling WordPress), please let me know. This is beyond anything I know how to cope with. And Arvixe, my hosting company, isn't terribly technically competent at the best of times.
Update: I just reinstalled WordPress and it fixed most of the issues.
