Hi
Got a strange problem with aJFBC login : I forward to an article with a php script on it stating this:
if($lastvisitdate == "0000-00-00 00:00:00" && substr($username,0,3) != "fb_"){
header("Location: /reset-password");
} else {

so I want the other users to reset the password but facebook users to continue.
Now when someone logs in with facebook, I get a server error
Server error
The website encountered an error while retrieving www.soslostpets.com/index.php?option=com...WVu&cb=1354211844233. It may be down for maintenance or configured incorrectly.
Here are some suggestions:
Reload this webpage later.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.
clicking on reload I go ahead and it works fine, but I try to understand why I get this internal error transaition page...can you help?

You shouldn't use the header PHP command. You should implement it like:
$app = JFactory::getApplication();
$app->redirect(JRoute::_('index.php?option=com_users&task=profile.edit'));
With PHP, using header can cause errors as the page may have already begun rendering. Joomla takes care of that with the redirect command. Another benefit is that you can add a message to the page, like:
$app = JFactory::getApplication();
$app->enqueueMessage('Thanks for coming back! You'll need to change your password before you can continue');
$app->redirect(JRoute::_('index.php?option=com_users&task=profile.edit'));
Hope that helps, but if not, let us know where you're adding that code as the location in the flow of registration may also be a problem.

Thanks,
Alex

OK now: the problem is before I reach this file:
I have started with:
if(substr($username,0,3) == "fb_"){echo "you are now logged in";exit;}
and got same error, when reloading I ended up with (as excpected) : you are now logged in and a blank page...
Any idea where I could look ?

Best thing to do now, if you're getting an internal server error message, is go to Joomla's Global Config:
* Disable GZip
* Set Error Reporting to Maximum
* Disable any "optimization" plugins you have enabled

That will hopefully display a prettier PHP error instead of a generic server error message. With that, you should be able to track down the issue.

Keep us posted on how it goes, and best of luck,
Alex

That last one is the key. Not sure why the fatal error isn't showing up afterwards, but if a require_once is called on a file that doesn't exist, PHP explodes.

It sounds like you have the Virtuemart Profile plugin enabled, but don't have Virtuemart installed. Can you disable that plugin, and any other profile plugins that are enabled for extensions you don't have? That should fix you up!

Thanks,
Alex
