Anyone have any ideas how to revert to an older version of wordpress? I recently updated my network (of about 1200 sites) to 3.1.2 and it broke the permalinks on the the main site (but none of the sub-sites).
It appears to be the problem described here: http://wordpress.org/support/topic/wordpress-312-permalink-problem
But the resolution does not work. I have tried working with the .htaccess file, activating the plugin, nothing seems to work.
So, I want to revert to 3.1.1 until wordpress addresses this bug. I tried just manually uploading the 3.1.1 files, but all the sub-sites (and the main site) still say 3.1.2 in the footer. I tried doing an network update again, but that didn’t seem to work. Any ideas?
Or even better, some other ideas how to fix the permalink issue.
Thanks so much!
