Hi friends, for everyone having problems with custom fields inside the amp plugin template, just call them like this :
global $post;
$metas = get_post_meta( $post->ID, ‘your-custom-field-name’, true );
100% working 😉
Hope that helps !
If it’s a fresh install, and you don’t have anything to lose, you should try to re-install wordpress again. If it doesn’t work, you can also try to install another version of wordpress. You can also verify the images that you upload. Just some suggestions 😉
