Admin Menu Editor Pro (Business) 2.28

##### Added
* Optionally, you can make the plugin clear the option cache when updating all subsites in Multisite. This is usually not necessary, but may help with compatibility issues when using an external object cache. Use the new custom filter "admin_menu_editor-clear_role_cache" to enable this feature. Example: `add_filter('admin_menu_editor-clear_role_cache', '__return_true');`

##### Fixed
* Fixed a bug where collapsing a menu heading would hide menu items but not separators.
* Fixed a conflict that could trigger a fatal error in PHP 8. The conflicting plugin or theme has not been identified, but the conflict was most likely caused by somebody returning NULL from one of the "mce_buttons" filters.
* When a user is hidden, the per-role user counts on the "Users -> All Users" page will now be adjusted accordingly.
* Fixed some minor issues with the size and layout of indeterminate checkboxes on small screens.
* Fixed the `[ame-user-info]` shortcode not working in login redirects. It would always output "(No user)" instead of the actual user data.
* Fixed a warning caused by a conflict with plugins and themes that call the "login_redirect" filter with only 1 parameter instead of the expected 3.
* Fixed a subtle bug where AME did not correctly prefer submenu items when trying to determine the current menu item based on the current URL.
* Probably fixed a bug where menu items that use fully qualified URLs would lose their custom settings when the site URL changed (such as when migrating the site to a different domain).
* Fixed an edge case where the plugin would incorrectly show an "is this option enabled for everyone" checkbox in an indeterminate state when it was actually enabled for all roles but was not explicitly enabled (or disabled) for individual users.
* Fixed a rare bug where a top level menu and a nested menu could share the same submenu items due to a key collision.
* Fixed a minor conflict with "Google Analytics for WordPress by MonsterInsights" where the "Dashboard -> Welcome to MonsterInsights" menu item that is usually hidden would become visible when AME was activated.

Updated add-ons

##### Fixed
* Fixed a conflict with "Amazon Simple Affiliate (ASA2)" that caused the "Add ASA2 Product" page to crash with an exception. This change should also fix conflicts with other plugins that create meta boxes with invalid IDs.
* Fixed a minor issue with "Happy Elementor Addons" where the "HappyAddons News & Updates" dashboard widget didn't show up in the "Dashboard Widgets" tab.
* For submenu separators and menu headings, removed the colorful left border that would appear when you hover, click, or focus on the item. Headings will still have the colored border if the "collapsible headings" option is enabled.

##### Changed
* The option "Hide the Admin Menu Editor Pro entry on the Plugins page from other users" now also hides any installed add-ons. The option has been renamed to "Hide Admin Menu Editor Pro and its add-ons from the Plugins page for other users".
* The plugin will now show an admin notice instead of crashing with an exception if meta box settings are corrupted by a site migration plugin or a similar tool.
* Switched the JSON serialization implementation from the jQuery JSON plugin to `JSON.stringify`. While this should not affect most users in any way, those that use Internet Explorer may or may not notice some changes in the handling of Unicode characters (e.g. in menu titles).
