deliberatecreationproject on "Error message regarding permission to use features on site."

Hi,

Here's the url to the screenshot of the error:
https://deliberatecreationproject.wordpress.com/wp-admin/post.php?post=867&action=edit

The other challenge that I'm having is that it looks like my page isn't updating correctly on the admin page.

Here's what the home page looks like when I visit my website:
https://deliberatecreationproject.wordpress.com/wp-admin/post.php?post=867&action=edit

Here's what I see when I log into the back end and visit that page:
https://deliberatecreationproject.wordpress.com/wp-admin/post.php?post=870&action=edit (this is what it used to look like).

I also posted a new video on my blog page and it sent emails out saying I have a new post, but when I clicked the link, the new post wasn't there. I've since deleted the new post because I was going to upload it differently, but I can't do what I want to do without accessing the updated home page.

ugh. really really frustrated. Thank you for your help.
