Visitors cannot submit forms error

A community member noticed that the contact page on their website is not working, displaying an error message. They have temporarily replaced it with a direct email option. The community members discuss that the contact page was working until about 22 hours ago when the last form submission was received. They also mention that visitors are unable to submit forms. The community member who posted the issue says they published changes just a few minutes ago, and have published multiple times this week. Another community member offers to provide admin access to the page.
