[Solved]I'm going MAD!Lounge
Just recently, at the bottom right corner of my screen, I'm getting a purple coloured pop up from Google Analytics telling me about trackers etc. I can't find out how to get rid of it, I don't believe I've ever opened an account with them and this continuous pop up is annoying and intrusive, please help :(!
