Troubleshoot Site Issues

Tip #1: If the website is throwing a 503 Error, the server is not responding, try pinging the A record IP to look for a response. You can also try killing running processes on the server if you can access the control panel/cmd line (on windows try recycling the app pool).

Tip #2: If the site is throwing a 500 Error, the server is up, check the site control files (if WP, check debug, error logs, etc... rename plugin folder if absolutely necessary to disable plugins)

Tip #3: If the site is throwing a 404 Error, check for missing files, or incorrect file permissions (use FTP or a control panel file manager)
