Trying to simulate the issue, it happened the same (wp-admin/submenu_slug), and the solution is to add a priority value in the hook admin_menu. Here, I’m adding a sub menu to the plugin BackWPup. Note the priority 11: add_action(‘admin_menu’, ‘third_party_submenu_wpse_91377’, 11 ); function third_party_submenu_wpse_91377() { add_submenu_page( ‘backwpup’, // Third party plugin Slug ‘My plugin’, ‘My plugin’, … Read more
I’ve been searching around for the same answer to your question and running into the exact same issues, and really appreciate your thorough research. I’m definitely +1 here for proposing this addition! To attempt to answer 2) – I don’t think there’s a good reason to exclude it. I think WordPress’s taxonomy terms are woefully … Read more
Background: The reason why filtering with dynamic_sidebar_params doesn’t work with HTML is because WordPress strips HTML from Widget Heading in wp_widget_control() function like this: $widget_title = esc_html( strip_tags( $sidebar_args[‘widget_name’] ) ); WordPress also strips HTML in default JavaScript in wp-admin/js/widgets.js So without a customised solution, there is no default filter or option either with PHP … Read more
Solution 1 Here’s a solution that uses pre_get_posts action to override the original search query and search by post ID instead. This is the approach that I would generally recommend. /** * Allows posts to be searched by ID in the admin area. * * @param WP_Query $query The WP_Query instance (passed by reference). */ … Read more
I’d suggest disabling script concatenation and/or compression to see if that helps.

EDIT: The most common reason for seeing … Read more
If you’re using multisite, there’s a plugin you can network activate to disable the welcome panel on all new sites. It’s aptly named “Hide Welcome Panel for Multisite.” If you just want to do this for a typical (single site) installation, it’s also pretty easy. The welcome screen is shown for a user if a … Read more
This code seems to work well for me (in functions.php): $user_id = get_current_user_id(); if ($user_id == 2) { add_filter( ‘parse_query’, ‘exclude_pages_from_admin’ ); } function exclude_pages_from_admin($query) { global $pagenow,$post_type; if (is_admin() && $pagenow==’edit.php’ && $post_type ==’page’) { $query->query_vars[‘post__not_in’] = array(‘123′,’234′,’345’); } }
I know you say it’s not a nonce issue, but it clearly is. That notice is the default ‘This nonce didn’t check out’ message. I don’t know exactly why the nonce is failing, but that is what is happening. I would double check how your nonces are created and checked. If you’re using wp_nonce_field() make … Read more
The two directories, where plugins can be located in line with normal mechanics are: wp-content/plugins wp-content/mu-plugins
