Since that's a paid plugin and I don't know how it operates, I can't write down a script that is capable to switch from that plugin to MyFacebook Connect. It should be pretty easy though (as I guess it stores the users' Facebook IDs as I do, so it'd just rename the database column and create a placeholder for uninstalling neatly Lennart's plugin).
Hello here's my error when i intalling and activing the plugin: "PluginLibrary is missing. Please install it before doing anything else with myfbconnect."

^ 404 error of what ? can you post complete error message
Also ensure you are running PluginLibrary 11. I should add a version check in the next version.
It's always keep saying:
You didn't let us login with your Facebook account. Please authorize our application from your Facebook Application manager if you would like to login into our Forum.
how do I troubleshoot this Sir?
Edit:
Got it working correctly

Thank You so much!
It's likely a misconfiguration problem. I'll hopefully release MyFacebook Connect 1.0.3 soon with a much improved error handling system so you can know what's causing the "Can't connect" issue.
Just some misconfiguration on my end. I accidentally put a space when I copied my app secret key.
