[Solved] Critical error on blog posts with WPdiscuz after Migration

@thedesignfreak,

Hi Asti,

I have tried your suggestion above and still having the same problem.

Thanks

I have also tried deleting and reinstalling the plugin but the problem still exists on my production environment. 

Is there a way to completely get rid of wpdiscuz before reinstalling? Because my settings and stuff did not get removed after reinstalling

Update: I have solved the issue by deleting the old comment form and recreating a new one. It is showing up without any errors.
