How to disable auto hide of WordPress dashboard Sidebar?

Do you have a plugin installed that is hiding the dashboard sidebar?

I am not using any plugin that would hide dashboard sidebar. It has been like this since I installed WordPress 3.5.1 on Hostgator.

I have following plugins installed.
Disqus Comment System
WordPress Importer
WP Super Cache

Is it possible that you are just noticing the changes that were made in WordPress 3.5?

Here is the layout you should see in 3.5.1.

In my case it’s always hidden. I unhide it and it will quickly hide itself right away.

I could try to reinstall WordPress which should install 3.5.1. Thanks.

Okay just did a reinstall of WordPress 3.5.1 and even fresh install of 3.5.1 comes with dashboard sidebar hidden.

Okay it has something to do with my subdomain. I created a new subdomain and fresh install of WordPress is as it is suppose to be. No Auto-hide.

I did clean and delete sub-domain folder. I should probably talk to Hostgator guys.

Thanks for your help.

It turns out it is a problem with WordPress database. Hostgator tech support changed mfold=f to mfold=t in database and everything seems to be fine.
