Adsense loading twice

Hi
I have a problem I can’t resolve. I use the same Adsense scripts in both my website and blog for a very long long time. Then around a month ago, I replaced my old blog Thesis 1.8x theme with Supermag. Everything was just fine until I included the Adsense scripts. Those scripts runs twice while they run normally with the old theme. Besides I use the same scripts in my web site running TYPO3 CMS without a glitch. I have never experienced a problem like this before and I’m screwed.
I have tried everything by the book and all I could find in the web without avail.
The question is: may I switch Supermag safely with Twenty Nineteen just for testing? Any special precautions?
Any advice will be appreciated.
Thanks
