I'm having a real problem installing this mod. I did it twice; I've installed modifications manually before (on phpBB2) that have worked fine, but I can't seem to get this one to 'stick' and it's a really important mod that will make life for the admins of my board much, much easier.
I checked and re-checked; the new tables are in my database, all the code has been put where it should have been put, and all the requisite files have been uploaded. But my board hasn't changed one bit. I go to "Manage Groups" and there is no extra field for Auto Groups, like specified in acp_groups.html . I rechecked that the code was okay in acp_groups.html, and there is no problem.
There may be one issue: the table for my groups in my database (MySQL) isn't called phpbb_groups, it's called phpbb3_groups. I changed phpbb_groups to phpbb3_groups when I submitted the query (I had submitted it as phpbb_groups before and then realized, after nothing showed up in Manage Groups, that my tables had a different prefix. But still nothing after the prefix was amended in the mod).
I'm at a loss. I love the idea of this mod and need it quite desperately for my forum (in which I have many rank-based fora viewable by only groups of a certain rank). Right now I have to add posters manually to rank-groups (or take them out!) and it is a nightmare.
