Uncaught SyntaxError: Invalid regular expression: /+/: Nothing to repeat

[CodeByFlo]

Hi Konsalex,

You helped me once before, and I would like to ask you one more time about the following issue:
On safari everything works well, but one chrome and Firefox I get the following error:

Uncaught SyntaxError: Invalid regular expression: /+/: Nothing to repeat

This is the link: https://alivetoearth.org/nl/product/compenseer-je-vlucht/

What could be the issue? I don't think I changed anything on my side.
People are really using this so all your help would be much appreciated in fixing this.

Best regards,

Florian

I'm sorry I think it was a caching issue, it's working now when I excluded it from caching
