Error

Error #0261: not enough rights to delete messages in the text conferences from the local database

 

Error description

No permission to delete messages in conferences from the history in your local MyChat Client database. In MyChat, it is possible to delete a message "for yourself", leaving it on the server and other conference users, but delete it on all your devices in the local cache.

 

Problem solution

Make sure that the permission group contains the "Delete any messages in conferences in own local database" rule enabled [198].
