I am sorry about the problem you are experiencing.
Our Development Team checked and found an issue in this regard. Your Galleries have been unpublished. For now, you can publish the Galleries and they will be displayed for you.
Also, we will update the plugin with the fixes applied to it as soon as possible.
I am glad to inform you that we already fixed the issue and updated the plugin accordingly. So, you can bulk publish the galleries, save the changes and the issue will be fixed for you.
Please let us know whether you have tried to bulk publish the galleries and check the case in that way or not.
Please provide us with the screenshot of the Galleries list page so that we can check the settings configuration. Also, please provide us with the link, where we can see the galleries and check the case.
Thank you.
P.S. Please feel free to open a new topic each time you have new questions/problems so that the information can be accessible to other users as well.
