I am battling this same issue. I began using the Equalize Digital Accessibility Checker on September 16, 2024. It worked great for about a week and a half, then I saw a notification that my website is password protected (it is not) and that the free version would not work on it. I no longer see the notification, but I cannot see my Accessibility Checker either. I can view and modify settings for it in my WordPress Dashboard, but the Checker itself never shows up on my pages anymore.
