INDIVIDUALIT:
cannot find documentation how to implement the #joomla access-level field in an own extension. Its just about front-end viewing permissions
INDIVIDUALIT:
@plinde check permissions of the tmp directory, and try sugarsync and an other server. Ask your provider if he blocks something
INDIVIDUALIT:
@plinde please send me your joomla admin details, I will try to check it tomorrow
INDIVIDUALIT:
@plinde can you please report more about the software versions you are using? Check also the server logs if accessible
