Can not install on my local mashine, fatal error ;((

Hey a.mozilla, are you attempting to install on top of an older version of the plugin / update an existing build? Or are you trying to install fresh?

It looks to me like there is some sort of conflict with the relic of an Events Calendar Scheduler plugin you’ve got; if you deactivate/remove that and try again, you should have better luck. Let me know if that’s not the case though.
