Until a couple of days ago this app was working OK. Nothing has changed, and I have checked through all the settings, but now I get this message and it doesn't publish.
Facebook is not reachable from your server: SSL certificate problem: unable to get local issuer certificate Check your connection! [Error occured at line 499] Your connection options could not be validated.
I tried contacting the server, but they say this is a plugin problem.
Does anyone have any ideas how to proceed from here?
Any help much appreciated.
