Thread:Extension talk:VisualEditor/VisualEditor doesn't show: Error setting curl options

Hi there, thanks in advance for your attention and thanks for your amazing work on VisualEditor!

I'm trying to get VisualEditor to work with my MediaWiki but instead I get the following error via a popup in my browser:

My configuration is:

MediaWiki 	1.22wmf14

PHP 	5.3.2 (apache2handler)

MySQL 	5.1.46

VisualEditor (Version 0.1.0) 	(bdd1a73) 01:07, 30. Aug. 2013

curl 7.21.4

Any clue why curl or the api could be a problem here?
