Activating the Premium Packages plugin without eShop installed, results in a message that eShop is not installed. But when eShop is installed but not activated on the main site, the Premium page just remains empty. In the logs, I see:
PHP Fatal error: Call to undefined function eshop_cart_process() in /xxx/xxx/xxx/wp-content/plugins/plugin-premium-package-manager-for-wp-networks/lib/class.post-type.php on line 257
Activating eShop on the main site fixes it of course, so there is no real problem. Just that it would make it more user-friendly if there was a message in this case too :)
Another suggestion: it would be nicer if the message on individual sites
Check out our Upgrades for more features and enhancements. and the My Account page could be hidden until there are actual Premium Packages configured on the main site...
Anyway, thanks for this great plugin!
