Problem with category view pictures

I have already almost ready to run my site with this fantastic template. I noticed that I have problems viewing the subcategories in Explorer and Chrome. Curiously looks perfect in Firefox (the browser that use default) in the attached images you can see what happens. Seems to be a CSS problem?
Thank you very much for your service!

Can you attach your site url here ? so i can check it and help you easier ?

Thanks

oh! Yes...

On the other hand, I have a problem with the menu when I choose product category. Thanks for everything, I am very grateful.

Hey. In the end I decided to reinstall the template and the products to fix the error from the menu disappears. To avoid the problem of the categories I installed the component tree categories in Phoca. I think at the moment and I have solved all problems.
