I have a problem with a WordPress plugin in my site. It's not working since yesterday.
The call giving me the error is
file_get_contents(http://cdn.api.twitter.com/1/urls/count.json?, and when the request fails, it gives this error:
failed to open stream: HTTP request failed!
I have tested to do a
curl with the URL, and it works in every place but this servers.
Is there any place in which I can see if my IPs are blacklisted and a method to whitelist them?
