Page Builder Plugin Failures

[bpyfrom]

My wordpress installation went well and deployed locally and to the cloud without issue. However, whenever I attempt to install a page builder plugin, on activation it either 1) fails to load properly or 2) it crashes the site (localhost and appspot) and shows a Fatal error that has some version of : Class 'xxx' not found. I have tried various page builder plugins such as:
Siteorigin page builder (wont load), live composer (crashes with fatal error), elementor (wont load), beaver builder (crashes with fatal error) ...etc.

The error from live composer is the following: Fatal error: Class 'DSLC_Html' not found in C:\xxxxx\wordpress\wp-content\plugins\live-composer-page-builder\includes\functions.php on line 141

Some help would be appreciated.

Thanks!

You have to install/update plugins and themes manually.
