Major Issue Customise via Safari Web Browser

Hi I'm a Mac User and I am unable to get any of the customise options to load at all using Safari. I am using Catch Base Pro. This used to work fine but has now stopped working. This needs to be rectified as soon as possible, or you need provide details of what I need to do to get it working, The customise functionality works fine in Firefox, but that is not a satisfactory alternative for me.
