$ causes error.

Just to note — using the HTML entity for dollar sign resolves the issue, but I’d still call it a bug.

Interesting, I was sure this had been fixed; in my test site I can enter dollar signs fine without issue. I’ll have a play around and see if I can re-create it.

If you a login on my site to test it, please let me know.

Ok, I have found the issue, will push out a fix shortly

Fix was released last night, you should now find this issue is resolved
