Not Found: PHP mapi extension not found
If you have upgraded zarafa, please restart Apache

Zarafa WebAapp can't start because of incompatible configuration.

Please correct above errors, a good start is by checking your '/etc/php/7.2/apache2/php.ini' file.

Or if you wish, you can disable this config check by editing the file '/usr/share/zarafa-webapp/config.php', but this is not recommend.
