Klicking on the "Mailinglist-Menü" leads to

In the meantime I did run an Update .

Running bin/OpenEMMInstaller.sh as root, I've checked the Update-Path:

After that I tried the option 9. Switch OpenEMM version

Currently active application versions:
Runtime: 20.10.075
Frontend: 20.10.000.128
TypeError: can only concatenate str (not "NoneType") to str

Maybe this is a helpful hint for the Error 500?

I would be thankful for a suggestion how to solve this issue.

Found the error finaly.

During the setup I did not completely enter all values at
Menu 2 and then Option 3 Change basic configuration.

As I did want to learn about the system first, I've left several fields like "mailaddress.bounce", "mailaddress.error" and so on empty.

After entering values for every single item, the error 500 has vanished and I can setup Mailings now.
But still they don't start or send yet. But that's another subject.

Maybe this information is helpfull.

I would like to suggest a better error-message than this 500 Error - explaining and claiming that this informations are missing.
It's a question of software quality, see ISO 25010 about functionality, reliability and usability for futher explanation.
