Ok. That fixed it. Clearing the cache did. I didn't read the yellow highlighted text "Have you checked our Help & FAQ section for the information? Have you read our tutorials? Have you ensured you've tried everything in this post first?"

because the yellow highlight is visually disturbing to me. I have a condition called Irlen syndrome and wear tinted glasses and am quite sensitive to light.

So the fact that this important text was highlighted meant that i never read it and just tried to avoid focussing on that part of the screen until I had scrolled beneath it.

Thanks for taking the time to read this and to help me out. Next time I will just do the steps in the article before posting.
