WordPress Upgrade Problem
I attempted to upgrade to the most recent version of Wordpress a few days back, but something was borked. The site worked fine for visitors, but I was unable to log in to the admin panel. I let it go for a few days while I tried to find a fix. Several Google searches and a request for help on the Wordpress support forums proved futile. I even dug into the Wordpress source for a bit to see what I could find, but the error message was rather cryptic. I realized after a few minutes that this would take way too much time and effort to debug. In the end, I restored the backups of both the database and the file system that I had made prior to upgrading.
Ironically, I normally don't back up anything before upgrading. I've never had an issue to date. I knew that not backing up is a bad idea and that it would only be a matter of time before I got bit. Fortunately, this time I decided to start backing up from here on out prior to every upgrade. After this little hickup, there's no question about it.
As for what to do now, I think I'll hold off unti the next release of Wordpress and see what happens with that one. I've got three blogs all running the same version of the software. I'd like to get them all upgraded right now. But, not going to touch the others until I get a version that works here.
