Hello Everybody,

I'm using K2 v2.7.7 (Developer Build) in Joomla 3.3.3 installation and I cannot get the JSON output to work when I type "my-domain.com/alias?format=json".

Here is the thrown errors :
1. Warning: Creating default object from empty value in MY_PATH/components/com_k2/views/itemlist/view.json.php on line 149

2. Fatal error: Call to undefined method JDocumentJSON::getHeadData() in MY_PATH/plugins/content/bt_socialshare/bt_socialshare.php on line 59

Notice that I get the output when I type "my-domain.com/alias?format=feed".

Can you please help me fix this issue.
Thank you in advance.
