Fb mass invite to like a page

Hi, I'm having problems with mass invites to like a page to my friend's list.
I tried Invite post likers to like page for Facebook - chrome addon
But it stopped to send invites after few dozens.
Script in the console also don't work.
Anyone have a solution?

Thanks

If anyone knows, can I learn?

I also have a problem with mass invite my friend. Fb is not reacting
