Why doesn't Facebook login work?

Question

PHP

Please help fix the authorization through Facebook!
Datalife 10.5 engine
boo.ee
1) If I set authorization via Facebook, as indicated in the Datalife instructions, then when I try to log in, I write " Unsupported social network is specified "
At the same time, the URL is indicated in the window:
boo.ee/index.php?do=auth -social&code=AQCme8_HbQfpp...
That is, the provider GET parameter is not specified. Is that how it should be? 2) If I specify " boo.ee/index.php?do=auth-social&provider=fc
" in the facebook application settings "Valid OAuth redirect URIs" , then I write an error "The specified URL is not allowed by the application configuration: One or more of the specified URLs are blocked by the application settings. The address must match the website or Canvas address, or the domain must be a subdomain of one of the application's domains. ". But the domain both in the redirect and in the application is exactly correct.
Where is the error?
