[Flatty Theme] Forum display messing up

[Gatas]

Hello ! 

When I create a thread in one of my sub-forums, some white squares appear and I have no idea why..

Also one of the sub-forum just migrated on the line above his normal position..

This user has been denied support.

Checked, was unable to find any issue at any point in the forum. If it occurs again try checking your css for the max width on the forum container.

Oh, you should've have checked rightafter I found the solution !
I resolved my problem some minutes ago, but thanks buddy for trying to help me !

For those who'll come here with the same problem... It was a permission problem to access some .css files in my cache.

So you should have to change the chmod of some folders/files to 755 to solve everything
