Webapp after Login - Apache Error 500 - no Log Entries

[Froschmedia]

Hi there,

I have a problem with Kopano webapp. After successful login, every user recieve an error 500, login was tried with different browsers.
If I delete the cookies, the login page is available again.

I switched from Debian 7 with Zarafa 7.2 to Ubuntu 18.04 with Kopano 8.7.9.
First I installed everything, put the attachments and the database on the new system. Everything works.
I think after configuring antivirus / antispam the web application doesn’t work. But I can’t find anything in debug log files.
Protocol activation in webapp / config.php does not work.
Mobile access with Z-Push works well.

my system:
ubuntu 18.04.4
kopano 8.7.9
z-push 2.5.2
webapp 3.5.14
php 7.2
apache

I found no solution on the web.

thanks

René

I found the problem. I tried with two Version of passwd as webapp plugin. This create a fatal error.
