Sorry again for proposing low level questions...
I'm working with the last version of PhPStorm an WAMPP server configuration.
After a couple of weeks I'm still fighting with debug configuration.
When I try to debug php on remote server, program stops at the code beginning but it is not able to step into or to hit any breakpoint.
File1.jpg shows the warning when the .php file is loaded and File2.jpg shows what I obtain when I click on "click to set up path mappings".
Starting from this point there is no way to setup path mapping so that OK button becames enabled.
