I tried to install konano-core from the community-downloads on an Centos 7 System.
I also used REMI-PHP-Packages so I could try the standard out of the box php, the php-Version 5.6 and the php-version 7.2
On every php-version Kopano works fine, and I can for example create users the the cli Command (so the MAPI works fine)
If I install the webapp I allways get the error with the missing php-mapi-modul.
Which informations should I provide, that I can get some help?
