G plugins crash site

I need a G+ plugin that won’t crash my site tlcoffeywrites.com
I have this plugin: https://premium.wpmudev.org/project/google-1/ set up on an identical blog alchemicalwords.com that was built at the same time and it works great. The sites have the same templates and I’m pretty sure the plugins and widgets are identical. They are also self hosted on the same server. I don’t know why it crashes tlcoffeywrites.com but it makes me sad because it’s exactly what I need. Can someone help?
