Try using the Web inspector in your browser (e.g. Firefox) to see if there are any errors on the page load.

Often for me this has been a permission problem on some of the files in the wp-admin folder which my host has sorted for me.

Switching back to the defauly Twenty Fourteen theme is a good debugging step. It will indicate whether the problem is with the theme you are using or not and is one way to narrow down where to look for the problem.

Perhaps take a full backup of files and database just in case first?

Do it still do the same when switched to the default theme (TwentyFourteen)?

Not had time to test this but something like the following:

<?php

/* check whether this is a child page */
if( $post->post_parent > 0 ) {

	/* get the post parent id */
	$mdw_post_parent_id = $post->post_parent;

	/* get the post parent slug */
	$mdw_slug = basename( get_permalink( $mdw_post_parent_id ) );

/* not a child page - has no parent id */
} else {

	/* get the post slug */
	$mdw_post_slug = basename( get_permalink( $post->ID ) );

}

/* load dyamic sidebar using slug */
dynamic_sidebar( 'sidebar_' . $mdw_post_slug );

?>

To add categories take a look here:

To add tags you can do that on the Post edit screen in the tags metabox. You can see the tags input box on the right of this screen:

Unless your theme specifically indicates that you need to add post meta I wouldn’t worry about it unless you are developing a plugin or theme, but you can find information on them here:

If your button is in a form then add a hidden form field. When the button is pressed the value of that form field is posted. Have you form post to the same page and then you can check on that page whether the form field has been posted. If it has include your function, if not show the page as normal.

There are a number of plugins for WordPress that do what you are after. I would start by searching the WordPress Plugin repository for members.

I know many speak highly of this plugin:

Found the answer eventually thanks for looking at the way other plugins have done this, most notably the Whistles plugin by Justin Tadlock. Below is my solution.

When register the post type with register_post_type you can pass capability types like this (for a custom post type named bulletin):

'capability_type' => 'bulletin',
'map_meta_cap' => true,
'capabilities' => array(

// meta caps (don't assign these to roles)
'edit_post'              => 'edit_bulletin',
'read_post'              => 'read_bulletin',
'delete_post'            => 'delete_bulletin',

// primitive/meta caps
'create_posts'           => 'create_bulletins',

// primitive caps used outside of map_meta_cap()
'edit_posts'             => 'edit_bulletins',
'edit_others_posts'      => 'manage_bulletins',
'publish_posts'          => 'manage_bulletins',
'read_private_posts'     => 'read',

// primitive caps used inside of map_meta_cap()
'read'                   => 'read',
'delete_posts'           => 'manage_bulletins',
'delete_private_posts'   => 'manage_bulletins',
'delete_published_posts' => 'manage_bulletins',
'delete_others_posts'    => 'manage_bulletins',
'edit_private_posts'     => 'edit_bulletins',
'edit_published_posts'   => 'edit_bulletins'
),

Then you need to assign the these capabilities to users on plugin activation (or another appropriate hook) to allow them to use the post type:

function mdw_plugin_activation() {

	/* Get the administrator role. */
	$mdw_role = get_role( 'administrator' );

	/* If the administrator role exists, add required capabilities for the plugin. */
	if ( !empty( $rhsstf_role ) ) {

		$mdw_role->add_cap( 'manage_bulletins' );
		$mdw_role->add_cap( 'create_bulletins' );
		$mdw_role->add_cap( 'edit_bulletins'   );
	}

}

register_activation_hook( __FILE__, 'mdw_plugin_activation' );

Thanks for coming back to me with that and I will take another look at the resource you have outlined. That was in fact the place I started however I could not quite get my head around it. Will take another look.

Thanks for your help.

Sounds like you just need to change the database connection details in the wp-config.php file on the remote site. They are probably different from your local connection details.

Thanks Esmi – that would be my next step!!

Also check the error logs with your host – they may give you a clue as to what is causing the error

Are you using theme other than one of the defaults – twenty[something]?

Sounds like you need to run a search and replace on the database to replace all of the old URLs with the new ones. The script below is great for doing this:

First thing to try is deactivating all plugins and switching to the default theme (twenty[something])
