Dear @global-former_user
Excuse me if i am wrong, but i am assuming that you have seen the troubleshooting page on the Lay Theme website:
https://laytheme.com/troubleshooting.html#empty-media-library
If that provides no change for your issue:
Do you have any third-party plugins that when deactivated temporarily resolve the issue?
Are Wordpress, Lay Theme and Lay Theme's plugins up to date and in-sync with each other?
do you have any custom code: HTML, CSS Javascript that when temporarily removed changes your issue.
If none of these options provide any help for you, could you please send your website address, /wp-admin/ username and password and a link to this topic to info@laytheme.com?
Let me know, I wish to help and apologies if my delay to reply to this has caused you any inconvenience.
Best wishes
Richard
