When going to the Sales Orders page (Sales > Orders) I receive an 500 Internal Server Error. I found one post which appears similar in that it discusses this problem, but which doesn't seem to really address my problem fully:

Checking the PHP logs, I can reproduce the following error when going to the Sales Orders page:
PHP Fatal error: Call to a member function setSaveParametersInSession() on a non-object in /data/html/app/code/core/Mage/Adminhtml/Block/Widget/Grid/Container.php on line 66
I've found a number of references while researching this error; however they refer to the problem resulting from a custom grid and this error I believe is coming from a stock install. Here is one such article:

Can anyone give me some pointers on how to move forward? This is Magento ver. 1.14.2.1, running on a 64 bit CentOS box.
