  • Same thing just happened to me, any help here?

    Wait, if you go to the plugins page (that lists all of your plugins) find the all in one calendar, THEN hit activate, seems to activate OK.

    This happened to me. I went through plugins, downloaded it, clicked activate, and it said “the plugin does not have a valid header.” I came on here, saw this message, went back to the plugins page, clicked activate, and it worked.
