Blank page after install. 18.04 LAMP (source)

View source for Blank page after install. 18.04 LAMP

Ubuntu server 18.04 with Kubuntu Desktop.

Did normal install on LAMP phpmyadmin for the database. Ran installed and all was fine. 

Location: /var/www/html/wackowiki

After install I only get a blank page.  View Page Source is also blank. 

Changed permissions to 777 all around.  Changed owner to www-data and nothing helps. 

Mediawiki in /var/www/html/mediawiki installed and ran fine.
