Thank you for contacting us and I'd be happy to assist.
I tried to access the website's admin area, but it keeps showing the message:
"ERROR: The username or password you entered is incorrect. Lost your password?"
Can you please check the username and password again?
Note: Your next reply will be private and making a complete backup copy is recommended before sharing the access details.
As a basic troubleshooting step, please also test this with all extra plugins disabled and the default theme like Twenty Twenty-One.
( especially test without any cache or optimization plugins which may be active )
The view named 'Attendee' is created and placed on the content template named '#Events Single Related Views'. But this content template is not assigned to any post type.
In the blocks-based views, for the relationship query filter to work as correctly, it is important that the template is assigned to the single post page of either the parent or child post type in the relationship.
Also since you're using the views inside the page content created in the Elementor page builder, it is recommended to use classic/legacy editor views. The blocks-based views are designed to work with the default Gutenberg block editor.
Any views that need to be placed in the Elementor template or page content, you can recreate them using the classic/legacy views editor and the relationship query filter will be available as expected.
I hope this helps and please let me know if you need any further assistance around this.
