Magento CE 2.4.2-p1 Installation Issue

[raminda]

Hi,

I'm trying to install Magento 2.4.2-p1 on Openlitespeed 1.7.11 with PHP 7.4. My operating system is Ubuntu 20.04. When I try to run the installation it shows below error,

PHP Fatal error: Uncaught Error: Class 'DOMDocument' not found in /var/www/html/demo/public_html/vendor/magento/framework/Config/Dom.php:449

It's more recommended to have Magento run with LSWS instead of OpenLiteSpeed. Because litemage cache only supported on LSWS and you might also want to adjust .htaccess file a little bit.

Could you share PHP info page, maybe this is due to some missing packages?

I thought you may miss the XML package, now I am not sure, maybe you can try manually install from the browser and see what it says.
