Spaces in credit card numbers

I think the reason is caching. The modification including a javascript file, maybe it was cached and it causes the error

Refresh the page (CTRL + F5) at that time should solve the issue

Glad to hear that it works well now

I did try that right away but it didn't work! (I also tried on a different browser.) It was only the toggling of something that seemed to make it work. I guess it's one of those things that's hard to debug unless others also find it and can pin down how to reproduce it!

Hmm, OK. I guess we will have to leave it as how it is now as I could not re-procedure the issue myself, too
