Pagination: sometimes displays negative page numbers

[jefferya]

If search returns less than 500 results (e.g. 350) and one navigates to the fourth page then pages with the number "0" and "-1" appear.

fix in place, needs some further testing before closing.

That problem seems to be fixed, but:

If less than 31 results, page four is still displaying with Results: 31-30 of 30 message ( where 30 was the total no of results)

This may be something happening when the results set is a multiple of 10.
