Social Network Integration for Joomla
JMP Social is used so that users can quickly register or login on your site if using their social network accounts.
Currently, this plugin supports accounts from: Facebook, Google, Twitter and VK. Most importantly, it's completely free.
It works with Joomla 3.8+ and 4.
After downloading and installing, you go to Plugins > System - JMP Social to start the setup.
In here, enable the services you want to integrate. Each service will have an instruction to get the required parameters:

See detailed instructions for:
Also you will see a field named Target (jQuery DOM). This is where the social buttons will be inserted:

With J3, please fill: .login form, #login-form
With J4, please fill: .login form , .mod-login
Note: This parameter may have to be changed if you use a different template or the login module is modified.
If you know CSS or jQuery path, you can use custom path.
I migrated about a thousand items with attachments from K2 using your tool and attachments plugin. I initially did this on a test account. Everything worked fine over there. The migrated article attachments worked fine. Then I backed it all up and moved it to my live domain. Now none of the attachments load. All I get is Exception File Not Found and I can't figure out where to look. Turning on error reporting and debug don't tell me anything. I am guessing the old files were not moved during the migration correct? Or how does that all work? I still have all the original folders in the original places as far as I can tell.
