I get the following error:

Warning: Division by zero in /public_html/shop/admin/includes/classes/split_page_results.php on line 47
For the following categories in the admin panel:

Catalog > Product Types
Catalog > Manufacturers
Catalog > Reviews
Catalog > Specials
Catalog > SaleMaker
Catalog > Products Expected

Customers > Group Pricing

Locations / Taxes > Countries
Locations / Taxes > Zones
Locations / Taxes > Zone Definitions
Locations / Taxes > Tax Classes
Locations / Taxes > Tax Rates

Localization > Currencies
Localization > Languages
Localization > Orders Status

I tried reinstalling the admin files but no luck? Anyone know how I can fix this error?

Thanks.
