It’s been suggested that - when I assigned my domain to the website, I must have put a trailing slash on the domain name. If that’s the answer, where can I fix that? Thanks
As that is not a code related issue, for which this forum is for, you would be much better suited going through Wix Support for more help on this issue.

Also, read the Wix Support pages too as it may be mentioned in there.

Hi thanks. However, I think I just fixed this. I had a trailing slash at the end of the canonical URL for the homepage. Having removed this, the double slash elsewhere disappear. If it reappears, I will do as you suggest! Thnx! Didn’t realise this site was purely code related… 
Hello. How did you remove the trailing slash for your homepage? I’m having this issue.
