JFBCSystem plugin

Hello,

In the error check I got the following error:

Test: JFBCSystem plugin is enabled
Fail: Not Detected! Please enable in the Site Config area of Autotune or in the Joomla plugin manager.

If the JFBCSystem plugin is enabled, but you still get this error, please check:
Your site is not in Offline Mode. If so, turn your site Online and re-run the Error Checker.
If you have a 'mobile template', disable it and re-test
Some templates have their own Facebook integration, and actively try to remove other Facebook extensions files. Try a different template.

Strange, I did not change anything in JFBConnect recently, and everything worked fine the last time I checked. Now it says that I need to enable a plugin which is already enabled. None of the points apply that I needed to check.

At the moment JFBConnect does not work, in spite of the fact that I have not changed anything in JFBConnect. I updated other components on the site but no new components or plugins were installed, only old ones updated.
I would appreciate any help
Thank you

Hello Alex,

Negative.

I disabled JCH pro plugin and the same problem persists. The problem is not the error check and the fact that it indicates the problem, the real problem is that JFBConnect simply doesn't work because trying to log in with Facebook or Google returns a HTTP ERROR 500, with a blank white page.
I made sure I cleaned the cache before trying to log in with facebook after having disabled the JCH Optimize plugin. I guess JCH may not have anything to do with this problem.
Any ideas?
I left the jch plugin disabled on the site for you to be able check, if you could.
I'm open to any suggestion.
Thank you and best regards
Aron

Here is the error message that I got after maximum error reporting was set in global configuration. I got it after trying to log in with Facebook

Catchable fatal error: Argument 1 passed to PlgSystemRedirect::handleError() must be an instance of JException, instance of Exception given in /home/onlinea1/public_html/plugins/system/redirect/redirect.php on line 55

Thank you

I found two socialprofiles in the plugins:

Social Profiles - Joomla
Social Profiles - Custom DB

Both of them are disabled and were disabled earlier. That didn't solve the problem. I enabled them but in vain. Nothing changed.

Hello Alex,

Unfortunately I could not solve the problem, JFBConnect is not usable for me. I'm at a loss, don't know how I could get it fixed. Could you pls give me more help?

Hi Alex,

This is what I did:

1. I disabled all the plugins, all of them.
2. I enabled the JFBConnect all necessary plugins and checked that the sytsem worked. It worked fine.
3. I started enabling the plugins them one by one and tested if the login function with FB works or there is an error message.
4. I found out that with sh404sef system plugin enabled, the strange problem occured
5. I went to sh404sef component in the backend, clicked on configuration and in the Component tab I set up JFBConnect to use joomla router.
6. I enabled the sh404sef plugin and voila, it works.

Now I try to re-enable all the plugins but I hope that was the source of the problem.
I'll be in touch if this occurs again, or the problem is not got rid of. I just wote down the steps of my solution in case other people out there run into the same problem.
