After a lot of pulling my hair out I managed to resolve the issue.
For anyone who might be struggling I will try to explain my fix.
I thought it was something simple that I was missing and thankfully it was - Happy days!
I went into the structure / content types / manage fields / types and clicked on manage fields.
Found the field that I was expecting the Editor to show up on and clicked on Edit.
Then clicked on Full HTML and Filtered HTML and clicked save.
Went to configuration / Development / Performance and cleared all caches.
Finally the editor shows up again for me.
Hope this helps someone who may be struggling.
All the best
