Hello. Thank you for contacting the Toolset support.
I checked the following page you shared:
- hidden link
Within what section you are trying to display the content using the "gridbuilder wp"? what content you want to display that is belongs to the author of the same post?
Have you added any hook that you shared as reference with your initial post "wp_grid_builder/grid/query_args"?
I will need admin access details and once I will review your current settings I will be able to guide you in the right direction.
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
