I have a "contact us" page with a script that has worked for years. Last week, clients started telling me that it was throwing an error message. When I tried it, I got this:

"[Error 110] Email template file /home/DIRNAME/DIRNAME.US/scripts/fh_emailTemplate_s.properties not found. Please publish your site again."

Looking back through the history of my site, there has NEVER been a file called "fh_emailTemplate_s.properties" associated with it.

I do not have any such file in my local system. There's none on the server. There's no such file in any templates that I've saved in the last 15 years of producing this site.

Any ideas why this might be happening? Better: any idea how to fix it? (I haven't done any coding in over a decade, so I'm UBER rusty on this.)
