404 on validation errors

Hi

I’m getting a redirection to a non existent page (the action of the form, mine is wordpressInstallation/#wpcf7-f192-t1-o1) when the user enters an email incorrectly.

I’ve been looking for an unsuccessful page or link in the plugin config, but if it exists I can’t find it.

Any clue? Thanks.
