When I try to add instagram embed through custom HTML, it does not let me update the post.
It gives error “updating failed” and that’s it, it simply does not save anything.
I used to add custom HTML with no problem before but latest 2-3 days, it simply does not work.
What could be the problem?
it generally means that WP doesn’t like something in your code.
Right Click > Inspect the page when it happens next to open the developers tools, in the console tab does it show any errors?
