After upgrading my version of WordPress from 2.5.1 to version 2.6.1 using Fantastico, I have found major problems using the WordPress dashboard and settings.

Whenever I try to create a new puppy food category or delete a post, I am getting a blank page and WordPress is unable to register any changes.

I have been using Firefox as my browser and Windows Vista as my operating system.

I am wondering if these problems could be related to plugins like popularity contest, WordPress Sticky or other commonly used plugins.

Even after disabling these plugins, I am unable to use WordPress 2.6.1’s dashboard or settings panels to create categories or delete posts.
Are there any known fixes?

I’d like one of my cat breeds categories to show only one post a page. Rest should follow the option set in admin.

So for this one category I’m using a new category-17.php file. with query_posts(‘showposts=1’)

But my navigation breaks down. ‘Older Entries’ link does not shows a Not found error. I do have more posts in the same category though.

Any suggestions?
