Changing the default port for connecting to PhpStorm
During a debugging session with Live Edit, the Chrome extension listens to the port of the JetBrains IDE from which the extension was invoked. Each IDE including PhpStorm has its own default port on which it starts.
If for some reason the default PhpStorm port is already busy, PhpStorm finds the closest available port and starts on it. This results in a conflict: PhpStorm is running on a "new" port while the Chrome extension still listens to the port of a previously started product.
The conflict reveals when you initiate a debugging session with Live Edit: the extension fails to connect through the default port, PhpStorm waits for connection from the extension and displays the following message with the port number where it is actually running (for example,
current port 63342):
To specify the actual PhpStorm port in the Chrome extension options
- Right-click and choose Options on the context menu. A web page with the Chrome extension options opens showing the parameters to connect to PhpStorm.
- In the IDE Connection area, specify the actual PhpStorm port in the Port spin box.
Overriding the default CORS settings
Suppose the page you are debugging with Live Edit requests a resource which is, for security reasons, protected against access through CORS settings. You can enable access to the protected resources by changing the Chrome extension options.
To override the default CORS settings
- Right-click and choose Options on the context menu. A web page with Chrome extension options opens showing the parameters to connect to PhpStorm.
- In the Force CORS text box, type the pattern that defines the URL addresses you want to make accessible, for example:
