[horde] Active Sync Error

[Andreas Mauser]

Hi,

everytinme I want to sync I get those:

HORDE[1478752]: #16 {main} [pid 1478752 on line 76 of "/var/www/html/wm/vendor/horde/core/lib/Horde/ErrorHandler.php"]

Message from syslogd at wm at May 16 08:41:31 ...
 HORDE: #16 {main} [pid 1478752 on line 76 of "/var/www/html/wm/vendor/horde/core/lib/Horde/ErrorHandler.php"]

There is no php.log.
What can I do? I see no approach for me to start looking.

Best regards,
Andreas
