In the Role Management settings, I'm getting the following message:
Warning: Invalid argument supplied for foreach() in mediatags_settings.php on line 395
It repeats the same warning three times and for each role listed underneath says "No user at this level." Admin, Editor, Author, Contributor, etc. For all of them.
Besides that the plugin seems to work fine but I'd really like to be able to fine-tune acceess and privileges.
