Solution to bug WP 2.6 for the templates of Pages

The version 2.6 and 2.6.1. WordPress has a bug when you go to create a new page, shows no templates or templates for your theme, nor any drop-down menu in the bottom section of Advanced Options.

I found 3 solutions, a strange, and another one on php, which I have worked, CSS:

1. In WordPress.org suggests a solution to this bug still not resolved. A strange solution but it has worked to some, this is to change the theme for another and reconnect to change in this way will re-read the directory of your theme and display templates.
2. In Frozr pose another solution is to edit the file in the directory wp-admin edit-page-form.php Specifically change the value 0 to a higher value, for example 110:

   if ( 0 != count( get_page_templates() ) ) {
function page_template_meta_box($post){
?>

3. As I do not have worked either of these two solutions I saw that they were the Advanced Options for editing pages, simply did not work on Ajax to deploy so they always for just showing off the property that the hidden file wp-admin.css directory wp-admin:

   1169. #poststuff .closed .inside {
display: none;}
