404 errors on social registration

I'm using the pop-up window option in a Joomla 2.5 site.

I have no problems when I click log in and then use the joomla username/password combination to log in.

When I click log in and then try to use the facebook or twitter buttons to log in, I get the window that says I'm being logged in but then I'm taken to a 404 error page.

Here's the URL:

Thank you for the response.

Are you using Joomla's built-in SEF features

Currenlty, I have SEF turned off...it's a template transition issue. Once I complete changing from one template to the other I'll turn it back on.

I do have USE URL REWRITING turned on and the other two options are off:

Add suffix to URL (no)
Unicode aliases (no)

Are you using a separate 3rd party extension for SEF URLs or 404 management

No

Have you modified your .htaccess file

Yes, below is the contents of my htacces file:

# Use PHP54CGI as default
#AddHandler fcgid54-script .php

Looks like that did the trick!

I updated the .htaccess file and cleared the cache and facebook and twitter log ins are working.

Thank you.

Actually I did combine the two files, leaving off the OpenSEF you said was for Joomla 1.0. So all seems to be working fine.

Thanks again.
