Hi emmanuel
Thank you for your reply.
In the meantime I installed a fresh and empty MODX on another website on the same server/provider and simply installed the Gallery addon via addon manager. The result is quite the same. It seems to be a server specific problem. The attached error message appears if entering the Gallery tab in the in the fresh installation's manager.
The paths in the system settings were as following:
gallery.files_path: [[+assets_path]]gallery/
gallery.files_url: [[+assets_url]]gallery/
Changing to server specific values do not have an influence. Directory permissions are correct. Actually MODX itself created the directories in the new installation.
You can see the output of phpinfo() at
http://modx.onlinefactory.ch/php.php . Do you see something conflicting with MODX?
Thank you
