On my blog http://planetblog.homelinux.org , the top 728x90 banner is showing fine, but lower down in the articles, the 468x60 banners are showing up as 728x90 banners all of a sudden. Why is that? I've double checked the code I put in so it should display 468x60 banners. This is in any browser.
Not to worry. I found the eMiniMall plugin for Wordpress. Once I used that all the Chitika looks ok again. You can get it from here if you need it.. http://x74.org/index.php/2005/10/02/eminimall-plugin-for-wordpress
Why you put <br /> at some of the chitika javascript code? I think this might be the problem. Try to remove it.
The <br /> is likely added by the Worpress code for some reason. As it's my only non hand coded page I can't be held responsible for rogue tags.
