Class Groups Permissions for 'all internal users' not working

Hi there! A couple items come to mind.

First, on the permissions tab for each of the impacted classes' properties you need to make sure that the "Allow users to attach objects to this class" setting is enabled, without this, users won't be allowed to create the class and this can prevent it from displaying in the document creation list. (Heres a reference in the User Guide: https://www.m-files.com/user-guide/latest/eng/Permissions_and_Default_permissions.html#permissions_and_automatic_permissions)

Second thing to check is to confirm the 'See this class group' option is set to Allow on the Class group permissions tab within the Class Group Properties. (Here's a reference in the User Guide: https://www.m-files.com/user-guide/latest/eng/adjusting_permissions-3.html)

Are you by chance using Deny on any user groups in the permissions? Deny settings will supersede any allow provided for that specific permission setting.  

Another thing to keep in mind with respect to troubleshoot items like is it is often necessary to fully log out and back in to the vault when permissions adjustments like this are being applied.  

Lastly, don't be afraid to reach out to support on this, often, cases like this getting eyes on the configuration allows us to better identify what the root cause of the behavior is.  Please let me know if any of what I've recommended has assisted you, thanks for posting and please don't be a stranger!

Problem solved.

It was the 'deny' option that I had checked.  Unchecking it fixed the problem.  

Thank you.

Excellent! Thanks for letting us know!
