360 Tour

I have newly installed h5p plugin on existing webpage. When I add h5p content (360 virtual tour) to a page (via a shortcode), entire page becomes unavailable: I get a 404 page not found error (within wordpress).

When I disable the plugin, the page works again (with shortcode writen where the content should be if plugin was available).

Any thoughts?

Using WordPress 5.8.1(Guttenberg)

with a custom child theme, based on Genesis Framework 3.3.5.

Hello to the H5P team, thank you for the recent module updates!
We are currently developing a kids' game with the VR360 Module here:
https://socalwatersierraclub.org/kids/hungry-hungry-sea-turtle/

1) With this update, we are no longer able to add text to any of the image or video popup windows, other than a hover "tooltip" created by the Title attribute. (Testing shows that kid players are missing the Tooltip) How can we include text above or below the image/video?

I am a new user and would like to know if I need to purchase an account to create different content?
