ISSUE SUMMARY:
I met with the "error Invalid Scopes: read_stream". After I made everything written in the FB app doc ( documentation.jomsocial.com/wiki/Setting_up_Facebook_Connect ) and in the solution topic ( www.jomsocial.com/forum/facebook-connect...s-read-stream#138129 ; and www.jomsocial.com/forum/facebook-connect...t-log-in-user#137831 ) the facebook login button perished.
Now there is only the text there.

(because security and testing reason the registration is off and the menu item [you can find it within főmenü as mënesh] is hidden from non registered users. I tested the facebook login with temporary allowed registration and public menu item of course)

BROWSER Chrome

Thank you!

Hi Albertus, as I wrote in OP I tried that. Changed the code, uploaded the files and this is the result... only text, without facebook login button.

Hi,

Hi Albertus,

Hi,

you can asking your server support about it.

Hi Albertus,

I wrote to the host company to do so. I will inform you about the results.

Cheers

After moving to a new hosting company everything is working fine. Thanks for the support!

Button is missing again. I got "undefined error" at registering with facebook, upgraded the files you mentioned earlier, now the button is missing - again.

Please make it work as it should be! Thank you

Hi,
do you made any changes at jomsocial files?

if you using 4.1.1 please do not put any bug fixes that related with facebook. at that version there is no any bugs that related with facebook.

please re-install your jomsocial if you made any changes.

Regards

Hi Albertus,

thank you but it's funny because I've got the "undefined error" with a clean 4.1.1. Install without any file modification.
I uploaded the named files _after_ I've met this error.
I'll load back the original ones to reproduce the error.

Tech updates: the main language is both of the joomla site and the facebook api: Hungarian

Best regards
Peter

Update:

after I reuploaded the three files the problem perished. Now the facebook login works. Strange
