Must be ME!!!!

Three days I have been trying to get Adsense on to my site.

I have placed the code in various areas, moved and deleted them.

Installed and activated the Site Kit plug-in as recommended by Google Adsense.
In the plug in it says it's activated, but when I click on the adsense icon it tells me its not and that I must be Offline - which I'm clearly not.

Can anyone help a dumb, not code savvy fool please,

My sincere apologies to the WA member featured in this picture but it is the only head scratching one I could find that fits with me right now.

Thanks in advance
