Permalinks effected by database? Really bizarre and persistent problem.

I've got a local site with MAMP that I'm developing. It's got a lot of custom development I've done, but it's all segregated into my plug-in. I was starting to work on some interaction with WooCommerce, realized it wasn't active, so I activated WooCommerce.

And that's when it happened...

My permalinks are not working at all. I'm getting a wordpress not found 404 (not a server 404) when I'm trying to access page post types. Single-posts are OK, but pages are not working. I had it set to post name structure for permalinks. The only structure that is working is the default generic ?=p32 or whatever the slug is for the permalinks based on IDs.

I started with the usual: change the permalink in the settings, change it back, save it a few times, etc.. Then I erased the .htaccess file, reset the permalinks and still, not fixed. Further digging, I went into MAMP's settings and ensured mod_rewrite was enabled.

Here's the kicker.. I set up a new folder, a new fresh install of wordpress, and a fresh new database... the permalinks work. I imported the theme I built, as well as all my plug-in code. The permalinks work. THEN.. I migrated my old database into that fresh install and suddenly, the permalinks break.

How can a database break permalinks?
