Check security.The /home1/lsvlokar/public_html/alexanderfritsch/blog/fotos/./qdig-files/ directory appears to be world-writable.

you may also want to allow the script to create world-writable
files using the following File Creation Mask setting:
Doing so will be more convenient but "less secure" than leaving the
umask setting as it is now. It will also bypass the security check
that produces this message.
