This error message means that your EA file was compile with old build of MetaEditor, and the system is asking to recompile the file.
Because MQL5 VPS is "Metatrader in cloud", and this "Metatrader in cloud" is having latest build but your Expert advisor was compile with old build.
It is what I understand from your screenshot.
