Hi,

fresh install of Kolab 16 on Debian 9 (Stretch). Everything works (mails, calendar, contacts, dirsrv, guam, wallaced, the works...) BUT chwala's "Edit" button (button is "grayed"/ somehow disabled.

I tried to go through Rouncubemail's "Files" interface: again, I'm able to create a folder, upload a file, download a file, delete a file, except "create" and "Rename" option. Both causes error message to be displayed:
An error occurred! Storage error. File rename failed.

/var/log/chwala shows the following:
T /chwala/api/?method=file_update)

• cyrus-imapd reconstruct found nothing new.
• all cyrus attributes for all files and folders under "Files" folders is "lrswipkxtecdan"

I run Kolab since 2005 from 2.x up to Winterfell and under various OSs, opensuse then CentOS 6-7.

2 weeks ago, I decided to start from scratch with Debian 9 Kolab installation (CentOS 7 Winterfell has been proven somewhat a bit too unstable for my taste). First time I'm having such elusive error...

the only whay to work around for now, is to download the file, edit the file independently (with gedit, vi or nano) then upload under a new name...

thanks in advance for your Help
