I had some problem (i dont know the reason) where my wordpress script woulndn't work ok, some modules wouldn't be shown for some file permissions (index.php files had "200" mod persmions), so when i set the permisions on those files at 777, all the script and the site works absolutely flawless... but... and here comes the but.
A few minutes later, its like if those permisions were set back to "200" and i can't again read the files and get the error.
what keeps changing these permissions back to 200?? I need them to be 777 or 755, and not changing back!!! I tried several times and it kept happening this thing. :(
