After update to new version I got always the "SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data" message, so I deleted the plugin, reinstalled it, but now there is no wpDiscuz comment box at all, only the default theme comment box appears? See at http://bircahang.org/1984-2/ - please help what to do!
Now the comment box appeared, however it gives every time a "SyntaxError: Invalid character" message.
Now I restored the original situation, now I have a comment box, but again the error message appears.
Solution found! There was a conflict between wzDiscuz and SI Captcha Anti-Spam plugin.
Thank you for letting us know.
