Error when hiding server ports (Trunk 794)

[rsmithgs]

When attempting to hide certain server ports in the server ports section I get the error:

ERROR: Only positive numbers are allowed !

When I click on apply. Though I don't get this error on another server with the same trunk. (The one I set up from scratch displays the error, the one I upgraded to the latest trunk does not display this error).

Anybody else have this issue and did you upgrade or fresh install?

Cheers
