[Bug / Issue] Channel Permissions Manager - Duplicate permissions = error

[LFWK]

When I try and use the Duplicate Permissions tool within the Channel Permissions Manager, I get redirected to the following page, with the following error:

That action could not be completed. Please try again, and if this occurs again please contact the system administrator and tell them how you got this message.

Any idea why, or how to fix? vBulletin 5.3.0.

I am sorry for the inconvenience this has caused. This is a known issue and we do not have a fix at this time. You would have to set the permissions manually.
