Well, I took the leap and installed the new version 2.0.1 version of WordPress. It mostly went OK, but unfortunately it broke my photo album (i.e. the only thing worth looking at). Thankfully it’s my own album so I just have a little debugging to do. I hope to have it back online soon.
I figured out the problem. For some reason, $_SERVER[‘PHP_SELF’] was behaving differently than it did before the upgrade. Before it would give the URL to the photos page, but after, it was always returning the URL to index.php. Come to find out, I didn’t need to use it anyway, so I think it’s all fixed now.
