Activating Plugin gives an internal server error

Hi,

I am using WordPress with GoDaddy as my host on a Windows Server using Plesk as my dashboard. I am running the latest version of WordPress and installed the latest version of your plugin.

The install works fine. After activating the plugin when I navigate to anywhere else on the site I get “500 Internal Server Error”. The only way to get back in is to rename the plugin directory so the plugin gets deactivated.

I tried this on a fresh install of WordPress on a subdomain with both the default Twenty Sixteen theme and copied over the Quark theme that I am using on my site where I first discovered this issue. On the test domain I have no additional plugins installed/activated.

Any help would be appreciated.

Thanks,
Devin
