I wanted to show the subcategory images on the category pages. I was following the instructions from this link.

Somehow I either deleted something and now my website is bringing up a fatal error. I have several Magento sites so I tried numerous times to copy the navigation.php files from the other site into the error site but its not working. Can someone assist me with this?

the message I am receiving is:

Fatal error: Class 'Mage_Catalog_Block_Navigation' not found in /home/public_html/app/code/community/Codnitive/Sidenav/Block/Navigation.php on line 25
