Part 1 - defaults (the DBG_LOCAL_BASE_PATH and DBG_EDITOR_URL)

1. in IDE:
   • open the /system/debug.php file for editing
   • comment-out these keys in the $dbg_options array: DBG_LOCAL_BASE_PATH, DBG_EDITOR_URL
   • save changes
2. in Admin Console
   • stay on the login screen
   • open the Debugger Report
   • use Inspect context menu entry on the 1st file editing link below an SQL query (has logger.php:265 text for me)
   • confirm, that shown URL:
     • is encoded (all the / symbols are replaced with %2F)
     • URL-decoded version of it looks like phpstorm://open?file=/path/to/file&line=line_number (/path/to/file - path to a file from the Web Server including Document Root; line_number - line number in that file)

Part 2 - custom DBG_LOCAL_BASE_PATH

1. in IDE:

     • URL-decoded version of it looks like phpstorm://open?file=/path/to/file&line=line_number (/path/to/file - path to a file from the Web Server, where Document Root was replaced with /Volumes/web; line_number - line number in that file)

Part 3 - custom DBG_EDITOR_URL
