I have a problem also with the logo image. What are the correct size? Where can I set the properties of the logo?

Do you have any suggestions?
Thanks!

Hi

GK Tabs is not displaying artcles. It only creates the module position a module which does that can be placed. You need to check in this exact module settings.

The logo issue is interesting, but You need to tell me how this shoud looks like, so I'll come up with best solution.
