Rosina, I just found the problem. It seems that you (or someone else) had modified the konstruktors.css file:

.bb-fc { float:right; clear:both; }

This CSS identifier (f — stands for float, c — means right, while a is left, b is middle) is used only for floating elements and it shouldn’t clear.

If an element is cleared on both sides, it can not have any block type elements standing next to it (in this case, on it’s right).

I suggest you replace that konstruktors.css with the original from a fresh download and that should solve the problem.
