1. in changed it directly in the wordpress-editor and i´m not stupid…..
There you can see, the actualy implemented, direct method. It does not work. And right, i can also not see it in the sourcecode of the page.
5. I put the code there, where it belongs, in the header, but not in the options of the theme.
When i did there, it was in line 378 or deeper, this info came not from me, it came directly from the google support.
and again, i´m not stupid, this is not my first tango with wordpress or wordpress themes.
