I've got a contact/membership form here:
which send the results to a database and for awhile it worked just fine and then recently when you submit the form, it does submit the info to the DB but it also brings up this error message on the results page:
Warning: mysql_free_result(): supplied argument is not a valid MySQL result resource in/home/content/h/u/l/hulastyle/html/membership5.php on line 57
So I checked line 57 which is one of the last lines of that page and this is what I got:
Actually the ?> is the code in question. Why am I getting that code? I'm enclosing the files in question.
Remove the code, upload the changes, try the form online and see if it works without the error message appearing.
