can you try this plugin:
https://wordpress.org/plugins/wp-add-mime-types/
then google for ".gltf mime type"
and then try the different mime types you find, i think you have to somehow put them into the plugin settings and then try if uploading a .gltf file works
I checked it out.
The theme is updated (5.7.1) but the carousel is not (1.2.3).
If I click on "Check for updates" it tells me that "A new version of this plugin is available." but it doesn't automatically update from Wordpress.
@cd Hi! Could you solve this? I'm having the same problem! And I've already updated LayTheme Version but everytime I update LYT + carousel addon + wordpress version, everything crashes and it causes a critical error on my website. So don't know what to do.. Please I would like some help! Thanks!
