I am having a similar issue.  The editor was working before the upgrade now after the upgrade the administrator and host users are seeing the full editor as before but any other  registered user who also has at least one other portal specific role (eg editor) is only getting to see the "bold|Italic|Left|Center|Right" menu unless I include a set of entries in the web.config for every role they are a member of. 

If we have to do this it is going to make the web.config huge as in our setup we have about 4 different editor roles and then we have 10 other portals running off the same codebase all with a similar number of editor roles. Only a few of which overlap with the same name.  Also how do the different settings work out any conflicts?
