But when I try to delete one, it says Permission Denied. Can you please help? We want to be able to delete our own branches.

Here is the error I get

May I know you are using on-premises Teamwork Server? or VP Online as your repository?

Hi we are using on-premises Teamwork Server :pray:

Would you please send us the log files of your server for checking? You can find them under the following folder of your server. You can send them to support@visual-paradigm.com to avoid publish them to the forum. Thanks!

VPServer\webserver\logs
VPServer\webserver\webapps\ROOT\WEB-INF\log

Okay thank you, I will share them as soon as I talk with the admins.
