Microsoft FrontPage not working
FrontPage is no longer supported as MicroSoft dropped support over 10 years ago. If you still want to use FrontPage to manage your website, you can install a free FTP software client, download your site to your location workstation, update the pages, and upload the pages/content you loaded.
There are other options available which you can Google or look on this site.
If you have any additional questions and need support please open a support ticket.
