I can see there's an error concerning the used favicon, but it's only with this page.
I just asked my template provider and got the following answer: „Kindly check that K2 item as when I assign that menu item id:6119 to Protostar - a standard template of Joomla, the same issue happens."
Unfortunately I can't find anything wrong with the k2 item id 1740. I created item id 1740 and a couple of others as a copy of another running item by changing only the content.
Disable the compressor for HTML you're using. It breaks the output. Compressing HTML is not practical really. At most you save a few KBs. If you optimize your images or use less JS or cut off unused extensions, the benefit is far greater.
