Hi, I just bought the JLex Review extension and it just doesn't work. I've configured everything but after I wrote a review and tried to send it to the server (after hitting Review button) it just opened blank page that said: {"status":400,"msg":"Setup too short."}

I really have no idea what the problem might be. I'm using Joomla 3.4.1 Stable and Purity III template.

Can you help me please? I'd really appreciate it.

Thank you very much
