Error 500 on logging in to ProxMox

[SelwynO]

The above error is displayed when logging on to Proxmox via the GUI.

See the attachment for the detailed description.

I would gratefully appreciate any assistance in resolving this issue.

Hi,

as I'm guessing the login over SSH still works fine, can you please provide the output of pveversion -v?
Probably some mismatched package versions, from the looks of it.
