[kronolith] Permission denied

[Silvano Rames Giuntoli]

Hello, I am using Horde 5.2.6, when I try to Export the Calendar I get this
message:

A fatal error has occurred
Permission Denied
Details have been logged for the administrator.

In the same time I can't find any setting in the Plesk control panel, can
someone give a hint ?

Thanks, best regards !
