Hi,
Yes, I am using the last version of the plugin 1.4.3 with WordPress 3.9.1.
This happens when I click on the button “Install Plugins” next to the button “Add another collection key” (just under the added collections list), the url where is taking me is:
…./wp-admin/admin.php?page=wpcore-install-plugins
But on the wpcore admin page, above the list of collections I have a message:
This theme recommends the following plugins: ….. and here there is a list of the plugins of the collections I want to add.
And if I click on “Begin installing plugins” which is in this same message it will take me to a list of the plugins with bulk actions, this url:
…./wp-admin/admin.php?page=install-required-plugins
And I can install them from this page correctly.
