Upgrade 1.4.2 to 1.4.3 - Can't view categories or events

[alphageek27]

I've upgraded 1.4.2 to 1.4.3 (J1.0.15) but in the admin area I can't see the categories or events.

Categories: Shows "No records found" but in the DB the events_categories table is populated with 6 records.

Events: Shows "Results 1 - 28 of 28", so I know the records there, but there is no list of events no matter how I filter it.

I compared the admin.events.categories.php and admin.events.html.php files between the two versions but the differences are minimal and the changes I made yielded no results.

Any help would be appreciated!
