On your advice, I read some more articles and posts regarding 404s with query strings. Many pointed to there being a single character that was causing the 404 – for example, a period. So I tried just removing the hyphen from the string and it worked. You all know much more about this than I do. Is that okay? Will the parameter still function without the hyphen? I have never worked with the particular web host before, and I am not enjoying their lack of response to my tickets. When they do respond, they basically copy and paste from their online documentation. I got nowhere fast.
Hi again. The host replied that they don’t block fonts, which they point out is proven by the fact that the other custom fonts (the arrows on the meta slider, for example) are displaying just fine. Could there be a problem with the path to the ultra-icons fonts? Thank you.
