[Owncloud] "Internal Server Error" when Accessing ownCloud Settings Pages

[Andi Sugandi]

Hi all,

I'm now having ownCLoud 4.0.6 installed on my VDS, creating files and
folders are OK except accessing all ownCloud Settings (Personal,
Users, Apps, Admin, and Help) pages ("Internal Server Error"):
http://paste.opensuse.org/view/simple/98804722

The error_log file:
http://paste.kde.org/533468/

I never found the issue when it was in previous releases. Any suggestions?

Thanks in advance.

Best regards,
