Seems to be some weird bug...

I've set Co-Op on Definethis.org yesterday in the evening.
I chose to show 5 text links in a line and everything was fine at that point but after a few hours, instead of text links there were 5 rectangles on the pages instead of text links.

Now, I've noticed that a new script is available, ad_network_281.php so I've uploaded this script, renamed ad_network_280.txt to ad_network_281.txt and changed the code on my php pages to include ad_network_281.php instead of the 280 version.

On the main page, the 5 links are showing fine but on other pages like this one I get an ad box and 4 text links. If you don't see it, you can check the screenshot

Another this, the checkbox saying 'Use "nofollow" on Ads' doesn't seem to work no matter the state (checked or unchecked). I'm using the code below to insert nofollow in the ad output:

echo str_replace('a href','a rel="nofollow" href',$ad_network);

PHP:

In case it helps the generated code is:

PHP:

 

I only see links, no rectangles

 

Clear out your text file and you wont have any more rectangle boxes.
