Removing The Add-On Upsell In Events Calendar PRO
A few users who are using Events Calendar PRO on client websites have asked if there’s an easy way to turn off the upsell — which promotes additional functionality in the form of plugin add-ons — on their installs. The upsell appears both on the individual event admin panel and at the top of the settings page (examples of both below).
If you’re using 2.x or above, there’s a bit of code you can now add to your wp-config file that will hide both the messages above. Add this:
Changing the ‘true’ to ‘false’ will bring the upsell back; it’s only hidden when ‘true’ is in place.
