I'm running two WordPress blogs. One is version 3.1 and the other is version 3.5. I've never tried updating the v3.1 blog, especially after all the problems I had with trying to update the v3.5 one. Last time I tried it, something got hung up really bad and the whole blog became inaccessible. It would still display fine, but I was unable to log in. It generated the same log-in error whenever I did. Finally I got it unstuck using another means of logging into it that I hadn't tried before. It had something to do with this site, but I don't recall the specifics anymore.
Neither of these blogs are heavily modified. I'm using fairly simple skins, I don't run a lot of plugins, and the skins haven't been tweaked that much. You can see the two blogs at the following URLs:
This is the v3.1 blog:
And this is the v3.5 blog:
I've looked around here but I wasn't able to find anything specific to improving my chances for a successful install here. If there is an article or section of articles on this topic, could you point the way please? And if there isn't, got any advice? I really don't want to repeated the problems I had with the v3.5 one.
