WP-print causes blank page in backend when updating posts or pages. Deactivating the plugin resolves the issue.
Tried the following:
1. (This hack by Lester Chan worked for WP3.2.1 multisite): In print-options.php, replaced
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>?page=<?php echo plugin_basename(__FILE__); ?>"> with:
<form method="post" action="<?php echo admin_url('admin.php?page='.plugin_basename(__FILE__)); ?>">, but no go.
2. Tried saving permalinks as default, then saving as day and name.
WP warns: 'The plugin generated 1 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.'
