There is probably unclosed html tags somehow within the module. Try using a different module and see if they are appearing correctly?

Looks happen with all. If I quit all the modules in Position-7 the right sidebar disappear but if I activate any, the bar appears but the module loads as in the screenshot I attached...

I updated the access in case you think is faster take a look.
Thanks.

Looks like ArkEditor is adding margin-right: 10px on the .pull-left class , http://take.ms/zE5aC

Can you try turning off ark editor and see how it goes?

You are the Boss Mark!
The problem was with Ark Editor. Choosing other editor didn't fix the problem, but uninstalling the package back all to normal.

Thanks!

Thanks for updating, glad that your issues are resolved now You should get in touch with the guy at ArkEditor and let them know that .pull-left is a common bootstrap class. Modifying the behavior of pull-left will result in a lot of abnormality because many extensions are still relying on bootstrap provided by Joomla.

Paul will definitely listen to your request, he's a nice guy
