After installing SEO Mod and using advanced mode my forum became invisible to Google bots and is no longer tracked, and I can't update PHPBB from 3.0.11 to 3.0.12 or install any mod or I get a 404 error.
My forum url is http://www.coinauctionshelp.com/forum/
I am thinking this is a Class settings issue since I have the same google analytics code, in the same file, as I have for the last 4 years without an issue. So it has to be a setting or two that needs to be adjusted or chosen. I am just stumped with this issue.
