Sorry to be a pain re: htaccess. I'm trying to upgrade from 1.2.6_RC1. Although I have not integrated Zenphoto with WordPress, the latter is in my root folder, so Zenphoto is effectively a subfolder within the 'root' WordPress.
Previous versions with .htaccess in the Zenphoto root always allowed it to display properly. Now I am getting a 404 error (page Not found - WordPress message) everytime I load the subfolder, despite editing the "htaccess" file (it's not called .htaccess?) in zp-core.
Any advice would be much appreciated
