When XAMPP starts, I am getting the error below. I have already tried all sorts of port settings (listen:xx, servername:xxx settings in httpd.conf, httpd-ssl.conf) provided in this SO question.
Error: Apache shutdown unexpectedly.This may be due to a blocked port, missing dependencies, improper privileges, a crash, or a shutdown by another method. Press the Logs button to view error logs and check the Windows Event Viewer for more clues
If you need more help, copy and post this entire log window on the forums
All of the threads with similar questions were revolving around one answer - "system port". I have already tried this and it didn't solve my issue.
