Cross-Domain Receiver Error - Ensure callback URL is correct

I believe the message you get will also depend on how you are going to your site in your browser. If you go to:
<!-- m --><a class="postlink" href="YOURDOMAIN.com/administrator/index.php">YOURDOMAIN.com/administrator/index.php - Then your connect URL should be YOURDOMAIN.com/">YOURDOMAIN.com/
<!-- m --><a class="postlink" href="www.YOURDOMAIN.com/administrator/index.php">www.YOURDOMAIN.com/administrator/index.php - Then your connect URL should be www.YOURDOMAIN.com/">www.YOURDOMAIN.com/

Yes!!!

The .htaccess redirect to make sure a user is at <!-- m --><a class="postlink" href="www.YOURDOMAIN.com">www.YOURDOMAIN.com and can't get to YOURDOMAIN.com">YOURDOMAIN.com makes sure no one can access your site in a way you don't want and will cause issues.

Let me know if this helps.

Something like that I want to do but my server doesn't support .htaccess. Is there another way to redirect?

Thank you!

My hosting provider fix the problem!!

But I have one more... When I connect with facebook, the system try to load <!-- m --><a class="postlink" href="www.site.com/component/jfbconnect/">www.site.com/component/jfbconnect/ but I receive error 500!!

The first time that I test it in IE, worked well.. But the other times don't.. <!-- s:-( --><img src="{SMILIES_PATH}/icon_e_sad.gif" alt="" title="Sad" /><!-- s:-( --> Why this happen?

Details:
Joomla 1.5.15
Community Builder 1.2.1

Joomla's SEO "friendly-urls" and mod_rewrite activated
Link for the New User Redirection: index.php?option=com_comprofiler

I have set the "Joomla Login Redirection URL" to the Community Builder's User Profile (only for registered users). Is it right or I must set it to something else?

Can you check the JFBCLogin module and see what your "Joomla Login Redirection URL" is set to?

You might try saving the module just to make sure the parameters are being properly saved.

Let me know what you find.

I' m very happy because I found the problem!! I have in my page the mod_facebookfans and this module conflicts with jfbconnect!

But how can I fix it?? Is it possible? I think if i use the same API, maybe the problem will fixed.. Right?

I found it!!!!! The solution is very simple: If anyone want have the two components in one page, must use the same API... Thank you very much for your help sourcecoast!

The only problem I have now is that the facebook button sometimes is invisible in IE! If you know anything about this, let me know..
