If you have upgraded zarafa, please restart Apache

PHP Config error: short_open_tag must be 'on'

Modify this setting in '/etc/php5/fpm/php.ini'

Zarafa WebAccess can't start because of incompatible configuration.

Please correct above errors, a good start is by checking your '/etc/php5/fpm/php.ini' file.

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