Content box goes under the sidebar

I don't think the css is properly coded because a few years ago i had someone had something to fix it but i don't remember what that was . So basically i think its because of the resolution size or some relation to that which causes the template to screw up. Please help me !

Can anyone help?

 

You probably see this because the wrapper container isn't wide enough. Try making your website wider and see if the two columns sit side by side again

 

I think something has to be made static or something.

 

add a float:left; to #content
