I’m using Firefox on Win7.
Went to glowforge.com. I was signed in (don’t know if it matters.) Went to the FAQs. Went to When will my glowforge ship. Clicked on the “you can see your estimated ship date” link. Got a 404 does not exist error. Then I went to the bottom left hand side of the page and clicked on FAQ and was presented with a login page to zendesk.
I’m fine. I found what I needed. I don’t need a response. Just thought your webmaster may want to know about these errors.
