Hi Klas and Seblod community, I contacted template buider and he said to me as follow:
" Hello Louis,
the issue is not caused by the template but by the css of the CCK plugin you are using.
The grid layout from this plugins css in 'http://vinisfusi.eu/media/cck/css/cck.css' causes theses issues. You will need to investigate this with the developer tools of your browser and override the css in the custom.css for example.
I'm sorry i can not give any further advice how to solve this, but you should ask for support from the plugin author."
I hope to receive a support from you.
Many thanks in advance for your reply.
Louis
