Here’s the deal: I wanted to be able to temporarily see all the posts at once in the WordPress Administration, so I went into the wp-admin folder, and poked around, and became frustrated: it wasn’t that simple!
Go to /wp-admin/includes/post.php and scroll to line 517. You will see wp("post_type=post&what_to_show=posts$post_status_q&posts_per_page=15&order=$order&orderby=$orderby");
Change the posts_per_page value to whatever you want it to be. Note: deleting the code will not let you view all posts.
WARNING: I don’t ever like to modify the default WordPress files, because when they get updated, you’ll be screwed. This is a only a temporary fix. It will not last if you update WordPress.
I use LesterChan‘s Download Manager plugin, and it’s great. Good interface, simple purpose.
I recently found out that after upgrading a client’s site to WP 2.5, WP-DownloadManager was no longer working. I followed the documentation on the plugin website, including resetting the permalink structure, but nothing worked.
As sad as it is to admit (since the plugin has saved me thousands of clicks), Admin Drop Down Menu by Ozh breaks the WordPress image uploader. If you’ve tried everything WordPress tells you to do in order to fix that Image Gallery feature and multiple image upload capability in WordPress 2.5, and disable this plugin.
