Problems with category and payment modules in Internet Explorer

[beutos]

Dear Prestashop users

 

I'm trying to fix something, but unfortunately I can't figure it out...

When I visit my site: www.mobileenergyshop.eu/en with Internet Explorer the categories aren't displayed in 'one line'. With Google Chrome I don't have this problem.

 

Also (as an example) the contact page looks very messy, the payment module's aren't well displayed, they are now located under the message box.

 

Can someone please help me with this problem? Thank you in advance!!

 

Best regards,

 

Jaap
