I have overwritten the file you sent me and then updated the site to 2.1.0 but this results in a white website.
Then I tried to overwrite again the file you sent as bugfix and this solved the issue!
So I suppose the right procedure is: update the template to 2.1.0 and THEN apply bugfix 😝
In any case, will try this on my production site too, just to check! but I think the problem is solved!!
Thank You!
