same issue here. I updated to 2.6, tried to add a workspace but it didn't appear anywhere. The FO message was "successfully added ... " though.
The log file shows the following:
#1 ERROR: Error: chmod(): Operation not permitted in '/srv/www/htdocs/fengoffice/environment/classes/AutoLoader.class.php' on line 148 (error code: 2)
I don't know if the message is related to this issue.
Using a fresh installation, this problem doesn't exist.
