I posted this originally in the main forum but was directed here.
I am trying to upgrade from 3.1.3 to 3.2.1. I normally do a manual installation, but I also tried the automatic installation.
After the 3.2.1 files are in place, I cannot get to any admin pages. In fact when going to a directory like wp-admin it appears blank, but when specifying a wp-admin PHP page (e.g. wp-admin/index.php) it prompts me to download the file -- which appears blank.
The front page of the blog loads as well as posts and pages. When using themes other than twenty eleven I get some other errors and weird behavior. I'm getting not founds when navigating to sub-blogs (multi-site by directory). Not sure if that's because of their themes or this larger issue. When going to a sub-blog's wp-admin pages I see the same behavior as the default blog at /.
We have a few plugins and even tried disabling (and completely removing them) before install, but we're still seeing the same error.
Is anyone else encountering this? Any suggestions?
