I have one site on server - Modx: 2.2.2pl

Thx Opengeek for your help response.
I noticed when I updated to 2.2.3
I consistently updated version of Modx to 2.2.6.
And now I have an error on error.log Modx ))

(ERROR @ /index.php) Could not get table name for class: modFileMediaSource

Then I logged in by admin I normaly see in filebrowser folders tree and files.
But then i logged in by editor_user I can't see any folder tree on deferent media sources, any files.

I don't have any Media Source Access Permissions.

See https://forums.modx.com/thread/80014/could-not-get-table-name-for-class-modfilemediasource for more information on this issue. Should be resolved in upcoming 2.2.7 release.
