Plugin MM Forms giving 404 page not found error while submitting
December 4, 2009 by: adminPlugin MM Forms giving 404 page not found error while submitting any forms. This error occurs only because you have changed the name "your-name" to "name". Now go to MM-forms settings and change Name to you-name as given below.
<p><label>Name (required)<br />
[text* your-name] </label></p>


Thanks for the tip – didn’t work for me though. Not sure why, I have the pro version and it always worked before.
Oh well, back to the drawing board.
