This is my first post here so Im gonna try to make it as clear as possible.
Our client's website(we didn't developed this one) is passing through our firewall(modsecurity).
They have an facebook share button in their blog, so when you hit the button, it asks for your facebook account normally, and then a facebook sharing pop-up is opened with this message:

You can share the post in your profile anyway, but our client is complaining a lot about it d-.-b.
I already deactivated our firewall for test-only, and the message persists.
Does someone has any idea about how to "fix it", or if its a server misconfiguration or code problem?
