Please turn on development mode and report the error message:

To get some error code that explains what is happening when you click on save try this.

I used Chrome browser and Development tools (Ctrl+Shift+i) ,  Network tab and filter just XHR.

Clear existing calls and then while that dev tools are open, click on save. If debug mode is enabled you should get

some error and call will be in red with status 500. Also check Console tab for any JavaScript errors.
