short description
I just installed the new v3.2 on a new server (install from scratch) on Ubuntu 20.04.
First everything worked very well, ISPConfig could be opened, I made several settings and then I did some changes in the System/Server Config tabs for several services (mail, web...) and now I only get a 500-error and only the ISPConfig Logo is shown and the logout-admin button. honestly i don't know what setting was the reason, but it seems like something has the wrong datatype in database now...
environment
Server OS: Ubuntu Server OS version: focal 20.04 ISPConfig version: 3.2 - newest from today
