Do you have
Override Save All Action enabled under
Build>Illuminated Cloud>Configure Application on the
Validation and Deployment tab? That will be required for
CTRL+S to work reliably. Otherwise if IntelliJ doesn't think the file is changed, it won't fire a save event and the file won't be deployed. If that's the case, you can use
Force Save (
CTRL+ALT+SHIFT+F12) to force the file to be deployed to the server. If that doesn't work, please email me your idea.log because I'll need to see exactly what's going on. I could also do a screenshare with you later today if needed to debug the issue. My guess is that we'll get to the bottom of it very quickly that way.
