500 Internal Server Error on Activation

Hi there,

I am trying deploy the free Membership plugin on my staging server to test and it seems to install ok, but as soon as I activate it, I get a 500 internal server error on the admin side. The public viewing side of the site still works fine, it’s just the admin side that I can no longer access. I looked through some of the documention to see if there is something I need to do before acticating (permissions or something) to make this work, but couldn’t find anything specific. Am I missing some info that you can direct me to?

Thanks,
Jenn
