for those having problems with third party modules - so did i after the upgrade as it kept giving a 404 not found error.
try disabling permalinks for those modules in admin - if that works and you can now see the modules in the front end, copy over the rewrite information relevant to those modules in the htaccess file.
just one solution worth trying as it worked for me
