# Can't activate plugin

 * PHP 5.3.28
    Wordpress 3.9
 * When I try to activate the plugin on a multisite I get this error:
 * Fatal error: Cannot redeclare class Mixpanel in /…/public/wp-content/plugins/
   leadin/lib/mixpanel/Mixpanel.php on line 302
 * On a single site, on activation, no error (with debug on), but the plugin is 
   not activated.

 * Sorry for the issue and thanks for letting us know about the problem.
 * We haven’t rigorously tested LeadIn on WordPress multisite yet which is why this
   bug slipped by us.
 * The good news is I’m pretty sure I know how to fix it and will include a patch
   in the next version of LeadIn going out this week. I’ll post back here once we
   launch the fix.
 * Thanks,
    – Andy
