That is a WordPress.com site, which we really can’t help with here.
To clear up any confusion, WordPress.com and WordPress.org are two different entities: https://wordpress.org/support/article/wordpress-vs-wordpress-com/
WordPress.com has complete documentation and support contacts at https://wordpress.com/support/
With that said, they generally don’t allow iframe embeds, unless it’s a whitelisted provider, which Disco is not.
Hello James,
Thank you for answering my questions! A couple of years ago i got very good support in this forum for my wordpress.com site, so i returned. I know the difference in wordpress .com and .org sites, but thought the forum was for both, so i’m sorry about my post in the wrong place. Anyway you helped me, so thank you! Additionally i found out that wordpress only does embeds with non-whitelisted provieders if you i had a business accounts. Too bad.
