I have tried the suggestions in this post before with success. However, for some reason now I receive the 404 error that the page cannot be displayed. I notice in the URL that upon submitting the form, the url is changed to the servers path instead of the domain path. I've tried replacing the library.php file in my AppData as stated above. I also replaced it in the DataAssist folder in the site I am testing. I still get the problem. The only solution seems to be to remove this line:
if (function_exists("rel2abs")) $WA_redirectURL = $WA_redirectURL?rel2abs($WA_redirectURL,dirname(__FILE__)):"";
Attached is my page and again, I'm using the library.php file contained within this thread. Any suggestions?
