CiviCRM Community Forums (archive)

I enabled Search Engine Friendly URLS on my site a few weeks ago - not thinking that they would mess with CiviCRM.  Now when someone is trying to go through online contributions, they get a "Invalid Key" screen.

Does anyone know how to fix this?  Can civiCRM run with SEF Urls?  I really need it to if at all possible.  Everything worked fine before.

on further research - the issue is only in Firefox... not IE.

Any ideas?

Thanks Donald -

Brian with Lighthouse Consulting (http://www.lcdservices.biz/) and Design assisted me - I recommend him to anyone - he works with Joomla.  He was very quick in responding and very helpful in resolving my issue- here is what the problem was (I had seen this before on forums, but for some reason couldn't fix myself, so he added codes to htaccess):

It wasn't *really* a Civi problem. The url you provided did not use the www. form. Because you're using SSL for the site, Civi treats the root domain and www. form as two different urls (this is a product of the nature of SSL, which is very specific in how it defines domains that are secured under a certificate). So what was happening is that you directed people to http://ncheroes.org... for the event registration, the Civi session key was defined, but after pressing continue, they were directed to http://www.ncheroes.org... and Civi no longer recognized the registered session key. The reason it redirects to www. once you click continue is that in your Civi configuration settings file, the resource url is defined as the www. form, so that is what Civi uses for any internal redirects.
 
I added a couple lines to your htaccess file so that any use of the root domain redirects to the www. form.
