Software can handle as many users as possible, it totally depends on the server capacity. 

What bug does FB connect have?

As to the third-party plugins issues you will need to contact plugin developers to resolve your issues with their plugins

end in e500 with below errors :

go to your cpanel or ftp

ow_plugins/fbconnect/plugin.xml file 

open it and check the build 4NUMBERS build line

Billy, can you please uninstall plugin completely, remove it from Available plugin section as well, download new one from the store and reupload it back, see if the problem persists. You have old plugin version. 

I changed , Current version is 8320

I see you demo has such problem too

Do you have any special symbols in your username or is it just jessy?

not symbols

Have u any idea why that one doesnt works?

Billy, can you send me FB access details from that jessy account? I won't touch anything just see some things.

Hi,

Unfortunately, the Facebook Connect does not work for me on the side. First ever get an error message when you enter the APP ID and the Keys.

Error message: ". APP configuration failed Please check your APP ID and APP your password."

When I go to new settings everything is suddenly available and I have no App-ID and more ... Enter Key ??? :(

But if I want to register or register with my Facebook account, is only the "e500.php".



In addition, the plugin is suddenly no longer in German?



How can I fix these three errors? :( Greetings & Thank you.

regards and thanks

You have old plugin. It's been fixed in the updated one. Uninstall it completely. Don't forget to delete it from the available plugin section. Download new one from the store and configure it according to the tutorial: http://docs.oxwall.org/plugin-tuts:facebook-connect

i will test it :)

can you tell me why the german language is not set??? :/

Most probably the translation is not added you need to check it, but first follow the instruction above, to install the right version and properly configure the plugin, if the issue with the translation persists, I will give you the instructions how to check whether there's  a translation

i intall the new version. it works but the language is not set in german :/

i install the plugin and test it on my test-system.
why i wont get a information in my live system that a update for the plugin is available?

one point is still critical - i set the point, that users cant change the nickname. when i login with the facebook test account i can change my nickname ... why that?

regards and thanks :)

Probably there's no translation in the language pack for the FB plugin. 

Go to the admin panel and do the following : 

instead of this url: www.yoursite.com/admin/languages

you need to enter www.yoursite.com/admin/dev-tools/languages

and search by the keys. 

First you need to choose facebook connect plugin section in the drop down menu to the left of the search text area, then type some keyword: http://www.oxwall.org/ow_userfiles/plugins/base/7074-language_de_not_work.JPG

for example fbconnect and check whether there's a translation for these keys shown in your screenshot.
