I recently upgraded to WP 3.4.1 and EM 220.127.116.11. On links starting with "events/", a 404 error occurs. For eg; events/categories and events/tags both give 404 as well as my submission page events/submit-an-event gives 404. If I put the permalink to top level, ie. /submit-an-event/, it works fine.
Another issue I'm having is pagination. They don't seem to work after the upgrade.
