I understand…I just spent about 30 minutes digging through the site for the plug-in, and now my head is starting to hurt too . The documentation is a “mess”, and I’m not real thrilled that installing this plug-in requires editing the “core” files of both phpbb and wp. - that should make upgrades (especially important with PhpBB, given its security history!) a real “joy” (not!).
I’m not 100% sure I yet understand a lot of what I’ve read over there…and I know I’m not sure where the code you supplied was from (wp or phpbb, or the plug-in) - I am 100% sure that the installation seems to be pretty convoluted.
If you feel like giving it a try another time, whay don’t you start a new thread, or maybe you can find someone over on the wordpress.org support forum who has installed this puppy on Dreamhost.
It appears from some of the discussion on the author’s site that mod_security could be impacting the install also, and that is the “Extra Web Security” check-box setting option for domains (see Edit Domain in the Control Panel).
All in all, not encouraging indeed - and I don’t have a spare PHPBB and WP installation laying around to test it with conveniently.
Who knows, maybe it will all look better in the morning…
