Installing certain Plugins causes Error 500

[JamborJan]

Installing certain plugins like:

• Divi Builder
• Yoast

cause a grain to constantly create a 500: Internal Server Error.

Others like

• Piwik Plugin

work well. I know due to the special configuration of Wordpress on Sandstorm not all plugins work but destroying a grain completely should be avoided.

Debug Log after installing the Yoast plugin:
