Plugin Isnt working once I moved servers

Hi –

I recently moved my blog to a new server and host. It is now hosted on wpengine. However when i migrated the site, this plugin no longer works? I am not sure what to do. I do not want to have to remove and reinstall as we have over 130 different sites within our mulitsite wordpress.

Please let me know if you have an suggestions on how to fix this.

Thanks,
