wpDiscuz incompatibility with Web 2.0 directory

Hello, I’m trying to make wpDiscuz work with Web 2.0 directory plugin for commenting listings as I use your plugin on my website. There’s an incompatibility issue that has been discussed and solved here https://codecanyon.net/comments/17690419. The fix doesn’t work any more.
To be short, wpDiscuz commenting form doesn’t show correctly with this plugin.

Could you please have a look at it and find the error to make the fix work again?
Thank you.
