I found the problem, which is why the white screen in the browser instead of the tools. I tried to log in from remote servers from different parts of the world. Therefore, tell the system administrator, namely the person who administers the web server, what exactly is the problem with the server configuration file, namely the regional settings. I do not know exactly what type of server Firefly AI uses, here is a panacea that will solve the problem with the correct display of the site tools.
