HTTP Error (401) when uploading files

[Lars Vegas]

Hey, I'm a little lost at the moment and I hope someone can help me. I have 2 Issues.

# 1 (the bigger one) — I get an Error when uploading files via the backend with the following message:



although the rights are set properly. See:



And # 2 — I added another User and when he is editing the settings, he keeps getting the following Error:

Error: Unable to continue: Unable to write config file. CHMOD 777 the folders /data, /backups and their sub-folders and retry

Strangely enough the changes are still made. So this is only a bit of a blemish, as he can still edit the settings, but solving Problem # 1 is really important to me and i hope anyone can help.

Best regards
Lars
