Very odd permalink problem (pages)

Hello all,

I’ve been busy developing a custom BP network for a client, and it’s nearly complete but a new permalink / 404 issue has popped up and it’s driving me crazy. I’ve been using WP for years and years on every project, and I’ve never seen any permalink issue that didn’t just have to do with rebuilding the htaccess and going from there. The most frustrating part of this was everything was working smoothly and nothing significant changed that should have caused this. Some background:

• Install is of WordPress (latest stable, now latest nightly) and BP 1.7 (latest)
• Pretty Permalinks (using any structure) no longer work, except when they are not used (?p=)
• Buddypress component pages do work (for example /groups), but regular pages don’t (they return the theme 404 page).

Initially this cropped up yesterday after I decided to stop using CollabPress for the project management features of this particular site, mainly because I was adding so much more to it that it made more sense if I just used my own CPT and taxonomies instead. I disabled CollabPress and turned off the group functionality in BP, as well as registered my new CPT and taxonomy in my theme functions file. It was at this point I first noticed pages now returning my theme 404 page.

After rebuilding the permalinks and still getting the same issue I figured it might be best to clear the DB and start fresh anyways, especially since there were a number of CollabPress projects and other test posts. I figured at this point the issue would be fixed, but still nothing.

My htaccess is below, but I can not for the life of me figure out what could have possibly changed that lead to this. It’s not a theme or plugin issue, as I’ve switched to 2013 and turned everything off, and when doing so pages then appear to show the blog archives instead. :S. I even installed the latest WP, BP, and bbPress nightlies and the issue still exists.

It’s a very odd one. Anyone have any thoughts? Thanks!
