Server error 500 was created by leemcc

Hi Guys,

I installed JFBConnect, and uninstalled a sclogin module as i thought it was part of the joomla component slogin I was uninstalling.

So I tried to login via FB and it said Welcome and also Error email address already exists and failed to log me in.

Now I can't log into front end or back end of my site.

I am given a Server Error 500 every time.

Can you suggest a solution please.

Kind regards Lee

What is the exact 500 error message you're getting? The SCLogin module is used with JFBConnect, but it's not required to be installed. It also has no functionality in the admin area, so I'm not sure how that's related.

One thing I'd recommend is trying from a different browser (or clearing all your cookies and cache from your current one). It's possible your browser had some invalid cookie set which is causing the 500 error that only you are experiencing. A simple reset of cookies should at least get you around it to get into the admin area again.

Again, the SCLogin module isn't necessary, but re-installing JFBConnect will re-install it. You won't lose your settings if you re-install, so that should be pretty painless if you get to that point.

I hope that helps, but if not, let us know.

Thanks,
Alex

Thanks Alex,

I tried your suggestion, Firefox just hangs and Microsoft Edge says:

I apologize for the delay. My only suggestion that I can give is to make a modification to our JFBCSystem plugin to completely disable it on startup. To do so, edit the /plugins/system/jfbcsystem/jfbcsystem.php file. Around line 26, you'll see:

function __construct(& $subject, $config)
    {
        $factoryFile = JPATH_ROOT . '/components/com_jfbconnect/libraries/factory.php';

Update that like:

function __construct(& $subject, $config)
    {
        return;
        $factoryFile = JPATH_ROOT . '/components/com_jfbconnect/libraries/factory.php';

That return statement will prevent our plugin from operating. The JFBCSystem plugin is what enables all other features of JFBConnect. If JFBC is the cause of the 500 error, that should get you in the backend.

If you still have problems, you could try the same addition of 'return;' to the __construct functions of the /plugins/authentication/jfbconnectauth/jfbconnectauth.php and /plugins/user/jfbconnectuser/jfbconnectuser.php files, though I'm confident that won't make a difference if the JFBCSystem plugin is disabled.

Finally, if that doesn't help, all I can recommend is finding your PHP error log (you may need to contact your hosting provider to help assist) to determine what is going wrong during authentication.

Please let us know if that helps or not. We'll gladly do whatever we can to help get you going, but this isn't an issue we've seen before, so I don't have any magic bullets for you right now.

Thanks,
Alex

Thanks For looking into this for me.
I tried your advice but it made no difference.

I also found a couple of Directories that a full of files from the previous component I tried:
/public_html/plugins/slogin_auth
/public_html/plugins/slogin_integration

So I'll ask my host if they can restore an earlier site version and Ill try your component again fresh.

There are too many old files referring to Plugins etc, so who knows what is still active.

Eg.....
application/x-httpd-php odnoklassniki.php
PHP script text

I removed the code from the other plugin. I don't know anything about that extension, so there's no help I'd be able to provide there.

Restoring a backup is never fun, but I'm glad to hear you have one. If that's not too difficult, it's the best option. Having access to the PHP error logs would likely point in the right direction, but still may not get you to the bottom of the problem as quickly as you'd like.

If you do run into any other issues or have any questions, definitely let us know and we'll gladly try to help get you going as best we can.

Thanks,
Alex

Thanks for your help,
I have the site restored and removed the old component.

Just before I reinstall JFBConnect I wanted to check the user functions:
I tried to edit a user but again got a server 500 error again.
I have no idea what causes this. I can log in front and back end.
But am concerned I should find/fix this before your component is installed.
I am going to ask my hosting provider to check into this as it is beyond my skills.

Then hopefully I can install your component again.
I've used it in the past and been very happy with it.

Cheers Lee

Strange. Definitely not related to JFBConnect, which does make us happy, but obviously doesn't help you much.

I definitely hope your hosting provider is able to help you narrow things down. If there's something else we can do to help, just let us know.

Thanks,
Alex
