Hello,

Interesting problem: When displaying an item on the site, the author is not displayed even though it is properly assigned and the comments section is not displayed as well. Could you help direct my troubleshooting please?

The site is: www.logic2020.com/insight/new-wenatchee-office

Thank you.

This appears to be a template issue.
You need to address this issue to the template's developer.
