Look at my website.... wowallpapers.com

With Firefox and Chrome:
After you enter on post, you can see the wallpaper, in the right you can see the adsense (image), below wallpaper another adsense (text), the resolution and below resolutions you can see 3 adsense (linkunits) - 3 on the same line.

With Internet Explorer:
You can't see the image adsense near the wallpaper (in right, on the same line with wallpaper) and below resolution, these 3 adsense units are not on the same line.

Conclusion is that it can not put multiple adsense blocks or units on the same line...

Can somebody resolve this BUG? (this problem happens only on Internet Explorer...)

I don't see any issue - the site looks the same in IE and safari

Nop... Enter into a random post. Please use Mozilla Firefox or Google Chrome (like most visitors) and you'll see that I have near wallpaper (in the right) 1 adsense block, and below Resolutions you will see on the same row (line) 3 adsense (linkunits)...

Understand?

It's being caused because IE7 was funky and the line
'meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />' is forcing it to work like IE 7.

Edit header.php and remove line 5 which is

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

and that will fix it. It has nothing to do with CSS or Atahualpa or wordpress, just the way IE8 emulates IE7

Thanks... It works... Now, the site looks great with Internet Explorer

Thanks a lot!
