Error #0400: no rights for deleting conference history completely
 

Error description

A user does not have rights to delete history completely in conferences.

 
Problem solution

This error can occur when you use an alternative application to work with MyChat or work directly with MyChat Server by using the official open protocol. Make sure that you specified correct data in a command or function. 


Also, check if the rule for complete history deletion in a private dialogue is allowed for your user's group.
