I keep getting this error, and it seems like it has appeared out of nowhere. I've been working at my project for some weeks, and this didn't show up until now.
When I try to run my app on localhost, the error in the title is shown. I have tried adding $opts[CURLOPT_SSLVERSION] = 3; in base_facebook.php as specified in another post, but it didn't work. I really have no idea what should I do now. Can anyone give me a helping hand?
