Installing essential grid plugin crashes my site

I have gone through this process several times now. After installing the highend theme I get a message from WP telling me I need to install some plugins. Through the process of elimination I have come to the conclusion that it is essential grid that is the problem. Every time I install it, I get the success message and then when I try to go back to the dashboard page I get “Internal server error” I can’t uninstall the plugin through the dashboard either because I can’t access my dashboard. The only way I have found to fix this is to reinstall WP from the beginning and start over.

Any help on this?
