OK, I know this makes no sense, and I've searched in the WP and TXP forums, but I recently upgraded my TXP install (in root directory) and now my WP blog (in subdirectory) doesn't work.
When I try to load my WP blog, I get a TXP 404 error. That leads me to believe that the .htaccess file inside of my WP blog directory isn't working anymore. Because I can get to my wp-admin directory (which actually exists and isn't generated), just not any of the public blog (the generated content).
I really hope someone can help me figure this out. I've also cross posted this in the TXP forums and another forum where I can get tech help.
