Error when trying to edit blog on vB5.1.5

[jdj]

I'm not sure whether this is a bug or not but I'm reporting it in case anybody else wants to try it on their setup.

On one of the blogs on my live site I've forgotten to add some tags, so I've just hit the edit button to go back and add some, as I would have done with vB4.

What this does is give me the following error message

Edit Conversation: HTTP 200 - SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

Turn debug mode on in your config.php. Open the browser's debug tool (F12) and try again to see the actual php error. Look for the loadeditor ajax request. See sample screenshot below
