I have read this topic:
But can't repair this problem... I added extentions OpenSSL and cURL to the PHP at my hoster, but it didn't help... Facebook app settings are correst.
First time i was taking this message, when trying to connect to the facebook to autorisation; after i added extention cURL, i could connect to the facebook (enter my e-mail and password), but after that when i was returned to my site i take this message.
Maybe somebody can give me some hints?
PS: Sorry for my bad english. I hope you understand my problem
