Changed the “custom menu” behavior for protected pages and category pages. Instead of neutralizing the links in the individual menu items that represent protected pages, these menu items are now deleted. The next sub-menu item is then “moved up” and replaces it. Please note that this change only applies to so-called “custom menus” created within WordPress (wp-admin -> Appearance -> Menus).
Fixed/modified the behavior of the [i4w_inline_popup] shortcode. When clicking on the generated hyperlink, the popup would take place but the background page would refresh, thereby closing the popup.
