Chwala on Kolab 3.2 upload error

[Christian Hügel]

Hi,

after upgrading to Kolab 3.2 I'm not able to upload any files. I get 
following error:

[22-Feb-2014 15:56:48] PHP Warning:  array_shift() expects parameter 1 
to be array, object given in 
/usr/share/chwala/lib/kolab/kolab_file_storage.php on line 875

Btw. I have changed the url to https in kolab_files.inc.php

Any advise? Thank you.

Christian
