[an error occurred while processing this directive]

Hi,

I have a problem that only happen with the root site that for some reason between time and then the page fail to load and show this message:

[an error occurred while processing this directive]

I looked it up and the problem seems to file permission not set write so I added this PHP script to my main folder to check if there is any files with wrong permissions and it find these four :

File: /home/bankalaf/public_html/tamrah/wp-content/wflogs/config.php

File: /home/bankalaf/public_html/tamrah/wp-content/wflogs/rules.php

File: /home/bankalaf/public_html/tamrah/wp-content/wflogs/ips.php

File: /home/bankalaf/public_html/tamrah/wp-content/wflogs/attack-data.php

the script as I understand should fix it put the problem is whenever their permission reset it goes back to their old one. which are for some 660 or 664 I tried reset them using FTP but without luck.
