Snapshot getting hung up and not completing

I granted you access to this site to address a problem with Snapshot

It seems to be getting hung up on Plugins, I've tried now three times. It ends up with a blank page that says "loading" then nothing happens. When I go to the dashboard and to Snapshots, it shows one, but there is no size or anything there, no logs, etc.

Not sure if there is a debugging process. I cannot turn off or delete plugins, this is a live site, and it's actually very SMALL in size so I don't get why this is messing up; normally really good luck with the plugin. Thanks for your help!
