I'm designing a site that uses SHTML, but whenever I try to name my pages with the SHTML extension, I just get a file called mypage.shtml.txt. Did I miss something?

Some editors automatically stick .txt on the end of things with endings like .shtml and .inc

You just need to rename them and take off the .txt

if you're using Notepad, make sure you have "All Files" selected under file type. if it still adds the .txt, try putting it in quotes, "yourfilename.shtml" with All Files selected

Save your file as this:

"file.shtml" <--- WITH QUOTATIONS!
