I've searched all over the place for help on this and tried a few things with no luck, so I thought I'd try my first post here.
I installed wordpress in my root directory so I could use it as a CMS for my site. I created all my pages and set "Home" as my Front Page and "Blog" as my Posts page.
If I just change the blog URL in settings > general I get login errors. I had to edit the database in phpMyAdmin to fix it. I saw a number of forum threads on the same subject point to this codex post on giving wordpress its own directory, but I'm not concerned with having the core wordpress files in my root directory. That post doesn't address the problem. I don't think the permalinks settings is the solution either because there doesn't seem to be a way to make a custom permalink for one page.
