Digital Ocean and Bugfix specialist

Hello, I currently got a snapshot from digital ocean running. Now the domain setup and so on work so I can access everything by the domain again. All files are where they are supposed to be but the app does not work. I do not know if the mySQL database is still intact. Maybe also the config file does not work as the new droplet has a new IP. In general the [login to view URL] should either redirect to login screen for frontend or [login to view URL] should redirect to login for output screen the index file reads the url and envokes function. the function e.g. for login requires a php file which contains html markup. Currently I only get the error: Not Found The requested URL /screen was not found on this server. Your job is to get the app running again with the files on the server and SSH access. !!!IMPORTANT start your application with the word "Bugfix" to prove you have read the description. Thanks.
