Thanks for your answer @gappiah, but is there a way to use google products and remove its cookies at the same time? And are these cookies not GDPR compliant? If yes, then how is it possible to use google products and be GDPR compliant?
Thanks @bengreeley, there was a certain section with a blank background image in each page that I think was pointing to this image so I deleted it and it fixed the problem. I tried deleting section by section to find where the problem came from.
