J-BusinessDirectory - Call to undefined method JUser::getDisplayName()

When I assign an owner to any business created in the backend, I get the following message when trying to access the page of that business:

Call to undefined method JUser::getDisplayName()

If I clear an assignment from an owner to the business, I can access the business page normally.

That way, users can not create business on the frontend.
I can only create business on the backend, without an assigned owner.

I'm using:

- Joomla 3.7.4

- Community Builder 2.1.3

- J-Business Directory 4.8.3

Hi,

It seems that there is an issue with the Community Builder integration. Please set the Social Profile to none on general settings for now.
We will fix this issue in the next release.

Hi, George Bara

Using his instruction, it worked again.
Waiting for the next version, compatible with Community Builder.

Thanks, George.
