I am trying to setup instructor signup using Ninja Forms (as recommended in this video: https://www.youtube.com/watch?v=fEdUsMg4A5g) but the plugin will not activate - it is installed, but when I hit activate, it gives me a green bar at the top that says "plugin deactivated". Is there a way to fix this or another way to configure instructor signup? Thanks!
Update: when trying to activate, it gives me this message "Ninja Forms cannot be network activated. Please visit each site's dashboard to activate the plugin". I am using Multisite, but when I go to the subsite dashboard to activate the plugin, there is nothing there</span>
oh wow stupid mistake on my part - I was supposed to go to the plugin page and activate on the subsite only... sorry for wasting anyone's time!
