Try switching to the default theme, deactivating all plugins excluding Contact Form 7, All in One SEO and Classic Editor, and clearing all cache data.

Why you are advised to deactivate plugins and switch to the default theme.

Hmm sorry but it doesn’t change something. Can I give you the login details so you can take a look?
