No user registration after submitting payment

I’ve generated buttons for two membership levels. After visitors submit payment via Paypal, they’re being returned to a blank white page with the auto-return URL plus a long string of characters.

Thus, new members are paying for membership but not being taken to a page where they can register a username and password.

I’ve set my auto return url in paypal, enabled payment data transfer and set my identity token.

Ran the server diagnostic tool and it said that php module mcrypt was not installed but have since installed it and still no luck getting the registration page to come up after visitors submit payment via paypal.

Any help would be GREATLY appreciated! Many thanks.

That link returns a 414 error: http://www.checkupdown.com/status/E414.html

You need to contact your webhost to fix their limit for your site.

Hi Cristian,

Thanks for your response. I contacted my webhost and received the following reply:

——-
This would be correct if you were on shared hosting, however you have a server so there are no limitations. If your scripting is not working you will need to troubleshoot further as this is a website configuration issue.

…so apparently there is no URL limitation for the site. Any other ideas on what could be causing the paypal auto-return issue? I have my auto-return URL set in paypal… not sure where all the additional parameters are being added. Thanks!

It’s returning a 414 error, I see it when I try the URL.

What setting needs to change to fix that, though, I don’t know. I always just refer the site owner to his webhost and they take care of it.

If you have a selfhosted server and your webhost won’t do it for you, then you’ll need to ask your webmaster, or google how to change it yourself, I guess.

I’m sorry I can’t give you more details on how to change it, I just don’t know about server administration. :/
