In the header.js file for this mod, please edit this line:

"onFailure"     : function (error) { showerror = false; if (showerror) alert("Error: " + error); }

to read:

"onFailure"     : function (error) { showerror = true; if (showerror) alert("Error: " + error); }

This should send up an alert to let us know what is going wrong. (hmm, may need to add that to the settings page as a debug option...)

Error: Ajax Phorum API call succeeded, but the return data could not be parsed as JSON data.

When I look at the traffic that is generated by the module (using Firebug under Firefox), I see the following response from the server:

<b>Fatal error</b>:  Call to undefined function:  json_decode() in <b>/usr/local/home/httpd/vhtdocs/cantonese
/phorum/include/api/json.php</b> on line <b>62</b><br />

The json PHP extension not be enabled on the server, causing the json_encode() and json_decode() functions to be missing out. I thought I had taken care of that in the json API code, but it looks like something is going wrong in there. We need some debugging here.

Please open include/api/json.php. In that file, you should see the following code:

if (!function_exists('json_encode')) {
    require_once('./include/api/json-pear.php');
    $PHORUM['API']['PEARJSON'] = new Services_JSON();
}

What I'm suspecting, is that $PHORUM is not in global scope here, causing the json extension detection to get lost in the rest of the API code. Try changing this code to:

if (!function_exists('json_encode')) {
    require_once('./include/api/json-pear.php');
    $GLOBALS['PHORUM']['API']['PEARJSON'] = new Services_JSON();
}

See if that makes the interface work. If it does, then I'll update the core code to represent this change.
