I am very frustrated with the WPMUDEV plugins so far...they seem to NOT work more often than they work.
That said, I have just installed Events+ on a new website I am working on http://shaun.mrbmedia.org and when I go to Events+ I just get a white page. My theme doesn't load and nothing loads from the plugin.
I have already redownloaded the plugin and reinstalled it. Same issue.
You can duplicate this error by going to http://shaun.mrbmedia.org/eventsplus
This plugin is essential to this website.
