When I try to insert a mention using the mention editor in VE, the mention appears to be there but it is not displayed.
The API call to retrieve the visual representation returns the following error:
{"error":{"code":"(curl error: 7)","info":"docserver-http-error: (curl error: 7)","*":"See http://127.0.0.1:8080/w/api.php for API usage"}}
