I'm using the newest version out, whatever's on the top of the download page. This was a "New" install of the 1.5.1, although I did have the older version working on my 1.3.9 site. When I upgraded to the 1.5.1, I did bring my database along, perhaps something in there is causing havoc. The only thing I don't understand is I run two sites, and I upgraded the two of them at the same time, and they are very similar. Only one of them is giving me the issues though. Is there something I should look for in my database? I ran the un-install script just to see if that would work, but I still get the error whenever I do the install SQL.
