Plugin Crashes my Site

So I have marketplace. And a slew of other plugins installed on a development mamp multisite. And a separate install on a live server Both are Multisite installed. If I enable plugins on the hosted social site. The entire site disappears.

I can network enable plugins but not enable them on hosted wordpress, buddypress sites. What am I doing wrong?

Membership, when enabled made the whole site not show up. I had to manually remove the plugin.
