Resolved Website does not display after 10 years of working fine

Getting a HTTP ERROR 500 error in Chrome or a blank white screen on the Firefox browser when trying to access website. This site has worked fine for over 10 years. Guessing this is a result from the great server migration. Could you please help?

Blank screen often indicates a php error, it is possible that you would need to change the PHP version used on your account (the default version on the new servers differ from the default on the old ones). You'll find this option under "Extra Features" in DirectAdmin.

The error log would hold additional clues as to what could be wrong otherwise, you'll find those under "Systsem Info & Files" in DirectAdmin

Thanks Anna! You were right. Switched the PHP version from the new 7.2 default to the 5.6 older version in DirectAdmin and now the site works again. (Extra Features, Select PHP version, Current PHP version: 5.6)
