Can't book anything in a certain column, but fine on other days

[DB91]

Hi guysJust wondered if someone has come across this before, we've got this issue that at random times we can't book anything in our Lesson 3 column, it's fine if I select future days - I haven't come across this before, the issue is for staff and Domain Admins - I have attached a screenshot, it's the Lesson 3 section, just can't click into it to book anything for any lesson?Cheers!

Check that you haven't set a time you can book before. The green line indicates where HAP+ 'thinks' it is, and you can say you can book lessons up to xxx minutes before. It could be that this is set to something other than 0 which means HAP+ will not allow bookings if they are within that window. If that makes sense

Thanks for getting back to me Nick, where are these settings? I've had a quick look in the Booking System section on setup.aspx and the web.config in the Booking System folder? Thanks a lot. Dan.
