Installing Monsterinsight keeps crashing my website

Hi,

I’ve tried half a dozen times now to install Monsterinsights lite, and every time I complete the set up wizard, my site goes down, with the following message.

I have to deactivate and delete the plugin for my site to be restored to proper functioning.

I need to get GA tracking going and would really like to use MI Lite for this, and eventually upgrade to the paid service, if someone could please help me sort this out, I’d really appreciate it.

Thanks!
