Hi. This link used to work, and is still where you're pointed to by "hosted apps" / wordpress. Is it still live at a different URL, and if not is the content still acccessible somewhere? Thanks.
The Hosted Apps Wordpress platform was disabled quite a while ago (several years). However, you should still be able to get a dump of the files and database using this tool: https://sourceforge.net/p/forge/community-docs/Hosted%20Apps%20Backups%20via%20Shell/
You can then use the following instructions to install that backup into your project web space: https://sourceforge.net/p/forge/community-docs/Migrating%20WP%20from%20Hosted%20Apps/
