Problem Summary: using the cfajaximport tag does not properly load the RailoAjax.js resulting in a 503 error, missing file.

Solution: In shared hosting you will need to copy the file RailoAjax.js into the public folder (wwwroot directory for windows hosting, public_html for Linux/Cpanel).

Upon copying this file to the public directory, try reloading the page which should respond correctly.
