When I Edit (or Add) a PAGE, I do not get two columns even though I have it set to display 2 columns. When I Edit (or Add) Posts, I get the 2 columns, no problem.
I've tried turning off all plugins, it didn't make any difference.
There is a sidebar div being displayed, but that sidebar div is empty.
I've narrowed it down to an issue with the file /wp-admin/edit-form-advanced.php. Lines 233-239 where the sidebar should be output, nothing is being output. Here's that code:
<div id="side-info-column" class="inner-sidebar">
<?php
('page' == $post_type) ? do_action('submitpage_box') : do_action('submitpost_box');
$side_meta_boxes = do_meta_boxes($post_type, 'side', $post);
?>
</div>
Here's what this code is displaying when I Edit a PAGE:
<div class="meta-box-sortables ui-sortable" id="side-sortables"></div>
Instead the sidebar meta boxes are being output lower down in this file at Lines 303-305. Here's that code:
( 'page' == $post_type ) ? do_action('edit_page_form') : do_action('edit_form_advanced');
do_meta_boxes($post_type, 'advanced', $post);
do_action('dbx_post_sidebar');
This is a very basic install of WP 3.1.1, there's almost nothing special about it. Why is the sidebar not properly displaying on Edit Page when it is on Edit Post? I need help please to correct this.
