This is the forum and you can see it here:
http://informationforumgr.forumgreek.com/t3782p80-topic#8024

this has a lot of pages

and the difference here:
http://informationforumgr.forumgreek.com/t3866-topic#8025
^
this has just one page.

Please heeeeelp meeee!!!

Could you exactly explain what is wrong with topics that have more than one page?  I really can not see what is wrong.

Take a look at the below images:

This is a total mess.

Edit:
I managed to fix the big problem but i still have the widget problem. They appear at the very bottom of the posts...

Hi,

Add this to your CSS :
Display > Colors > CSS stylesheet

Code:

#content-container div#container { float:left; }

Thanks Ange! Problem solved!
