Hello,
I checked your site and don’t see the issues with the Static Block editing https://gyazo.com/1a20442df1e4f0eba2e9ace1463c55b4 Or with the Contact page editing https://gyazo.com/3c3fb858e9a005eef4c727db2f971829 The mentioned error appears if you try to edit archive pages as a rule (like shop page, blog page).
Regards
