Hey there

Sorry for asking but not clearly getting the point of the question, can you please rephrase your question? or, can you tell me how to replicate the problem?

Thanks in advance

As you can see on my Site www.compott.de, the H1 Tag is set but empty. How can i filled up this H1 Tag?

My Site Title is Set under the Apperance in Wordpress.

Is it more understandable?
