Hello

I have installed a new forum module 5.04.01 with public unmoderated/ private moderated forums. All going well with email notifications being sent and posts uploaded.

However, when I log out to view posts (or login to view private forum posts) 95% of the time I cannot see posts and get the following error message.

A critical error has occurred.
Object reference not set to an instance of an object.

I have reinstalled the forum and established a range of different users: admin, registered and superusers. Alas continue to have error issue.

You can view the forum at: the Heart and follow the forum discussion and click on threads with title  "Registered User" or "This is more than"  as an example of post that cannot be viewed and critical error displayed.

Appreciate your help as this is a very frustrating issue.

Thanks

Miles

Hard to say.  "RenderPostAuthor" method that causes the error have lot of code.
Try turn off all avatars.
