Put the following in your functions.php
:
if (is_admin() && ! current_user_can('install_plugins')) {
add_action('admin_init', 'remove_slidedeck_menu_page');
add_action('admin_footer', 'remove_slidedeck_media_button');
}
// remove the menu page
function remove_slidedeck_menu_page() {
remove_menu_page('slidedeck2-lite.php');
}
// remove the button
function remove_slidedeck_media_button() {
echo <<<JQUERY
<script>
jQuery(document).ready(function($) {
$('#add_slidedeck').remove();
});
</script>
JQUERY;
}
Note: I did test this. If something doesn’t work for you, please report back. If it does, please come back as well (and vote up/accept). 😉
// EDIT: the menu page is now working.
// EDIT 2: the button as well.
