@simone , @pietrogiordanoc ,
This is an old thread, please post a new thread and describe the use case you’re asking about.
That didn’t seem to work but what I suggested did work. There are lots of threads about this so I was just trying not to start a whole new conversation and leave the solution online.
I’ve used this and it works https://www.wix.com/velo/forum/main/comment/2205fa65-20ad-31b8-a6bb-34c022e3e9e4?postId=5a60bbeb61f2e70013139cc7
I owe YOU a coffee 5 years later!!
I was having the same problem. For a moment, I thought about just using the /pagename information, but after I decided to use the whole URL, the problem started. I forgot about the first idea and started messing with the code, but you saved me! 
IT WORKED!
