CiviCRM Community Forums (archive)

Hello: I put up my live contribution page, and tested it on my joomla powered CMS site. After I filled out the beginning information and hit 'next' i get this:

"Sorry. A non-recoverable error has occurred.

We can't load the requested web page. This page requires cookies to be enabled in your browser settings. Please check this setting and enable cookies (if they are not enabled). Then try again. If this error persists, contact the site adminstrator for assistance.

Error type: Could not find a valid key."

Cookies are enabled on both my MAC (firefox, opera, chrome) and Windows 7 (IE computers.

I checked the payment processor name and type. It's paypal standard. Under live i have the actual paypal email. I did not put anything for the page urls below that. In the test area i have my paypal sand box email and the default web pages there.

Civicontribute is enabled under system settings.

I'm unsure how to fix it. Past posts don't give a definitive answer.

It does switch from www.example.com to example.com. Where do I tell it not to do this?

Resolved the issue using an apache redirect, and formatting the url settings in civiCRM. Thank you,

In this case, CiviCRM has issued a redirect, at which point it uses the configured site URL in civicrm.settings.php.

When you first browsed to the site, you accessed via a different server (eg, CiviCRM is configured for www.example.com but being a lazy developer we all type example.com and save four letters).

This causes a conflict when the redirect is fired. The simple fix (and better for your site generally) is to use Canonical URLs and ensure all visitors access by the same hostname. (IMO www.example.com is superior, for advantages in browser UI, even though I agree that the www. prefix is generally pointless.)

In your situation, I'd set up an Apache redirect to ensure all visitors see 'www.example.com' all the time.

I use this myself (in your Apache config) -
RewriteEngine On
RewriteCond %{HTTP_HOST}   !^www\.example\.com [NC]
RewriteCond %{HTTP_HOST}   !^$
RewriteRule ^/(.*)         http://www.example.com/$1 [L,R]

According to Chris Hope's ElectricToolbox article on the use of WWW in website addresses above, this should work too, but I haven't tried it myself.
RedirectMatch permanent .* http://www.example.com/


luthien, if you're using the redirect i posted above, you need to ensure that the redirect is pointing to the same canonical url that civicrm is using.

post with details if you want informed replies (eg "i added the following config snippet to apache [ ... ], and my civicrm.settings.php has [ ... ]").

it may be simpler to remove the apache config and find a canonical url plugin for your CMS ... apache config alterations cut a bit deeper, so you want to be sure of what you're doing

Sorry luthien, that looks ok to me at a glance. You may have to debug a bit further ... lots of things (other than hostnames) may affect browser cookies. Might be best to start a new thread, and describe the issue you're having in as much detail as you can - you can link back to this one for reference, but it appears that the fix which solved the issues for menasor (OP of this thread) is not the fix for you
