Blank page for Ads module

Hello, 

Whenever i click on "Ads" module as admin i see blank page. The url is   mysite.com/modules/boonex/ads/post_mod_ads.php 

I also see blank page when i click on ads as guest.There are 2 ways to see ads in my site. The first is to click on menu "Ads" which gives you the message "ACCESS DENIED .PLEASE JOIN FIRST"  . I have activate the block "Ads" on homepage so the second way is to click on the title from the ad you want to open. If you choose this way you get a blank page . You should get the same message "ACCESS DENIED .PLEASE JOIN FIRST" . The url i get is mysite.com/ads/entry/ad-title  (ad -title is the title for each ad )

If i click on a specific ad as member i can see the ad without problem ( the url mysite.com/ads/entry/ad-title   works fine)

Any suggestions? 

Thank you 

 Make sure you have php error reporting turned on.. That white page is normally an error being surpressed because its turned off. Once you see the actual error it'll be easier to track down.

Hello mscott,

if you mean the cpanel error logs , they are on. Unfortunately i can't find any problem there
