Hi Jan,

I did only update Horde - shortly before or after I applied as well 
security patches. But php7 was already installed upfront (running on 
Ubuntu 16.04 LTS)

I now enabled the testpage to provide further details on php or other 
findings. It crashed, from php log with errors below:

2017-09-22T16:15:28+00:00 EMERG: HORDE [horde] ParseError: syntax error, 
unexpected 'new' (T_NEW) in /usr/share/php/File/Fstab.php:110
Stack trace:

bytes [pid 7335 on line 613 of "/usr/share/php/Horde/Registry.php"]

Regarding the trace below - if it was no error, why is the error handler 
called? For the issues I solved before, log looked similar. And SyncML 
is broken for all contacts, calendar and notes - so seems to be some 
"framework" kind of issue?

Any further ideas/hints?

br, Christian
