<br>
for a couple of days i get sometimes a HTTP 500 error when i try
to sync via Caldav and Davx on my android phone. But the access
to the webmail system was working.<br>
After a today update and reboot of the server i even can not
access the webmail system - i get straight a HTTP 500 error. In
the error.log from roundcube i found this [1]. Could this the
problem and if yes, how can i fix it?<br>
<br>
Thanks and Regards<br>
