[Solved] wpDiscuz dissapeared

Hello

I had wpDiscuz with reCAPTCHA enabled on my site. Suddenly, without updating anything (theme or other plugins) it has just stopped showing up. Instead it shows the stock comments system from wordpress.

This happened tonight. I know this because I started receiving Spam comments so reCAPTCHA was not working, and I checked only to find that wpDiscuz wasn't working either. 

You can see the site here:  http://bit.ly/2jErj5x

I tried to delete the plugin and reinstall it again, with no success. I have turned off cache and still not showing up. 

Also I have the site copied to a different location for development issues with the same plugins and theme, all of them updated as well (except reCAPTCHA 1.0.6 that doesn't allow to update) and it shows just find there.

Any clue as to why this started happening?

Thanks
