Hello,
I am getting the following error when I try to access G2 integrated.

The requested URL /main.php was not found on this server.

It points me directly to alpine9.net/main.php even though the link shows http://www.alpine9.net/modules.php?name=gallery2.

Directly accessing my site works:
http://www.alpine9.net/modules/gallery2/main.php

I read through the stickies and found a few other people with this issue where moderators pointed them to the sticky, but couldn't find how to resolve the issue.

Here are where the actual paths are for my settings in the admin section of the integration file:
Full path to your Gallery2 directory: /usr/local/www/data/modules/gallery2/
URL to your embedded Gallery: modules.php?name=gallery2
The relative path to your Gallery2 directory: /usr/local/g2data/ (this is the full path and not sure if it's asking for where the g2data folder is or something else?)
Active User ID: 0

I read through the readme for integration and couldn't find any additional details.

I also have caching on, so could changing my settings (I have been playing around some and keep getting the same error) not really be showing from the caching?

Thanks for your help!
