DiaryBook 7.4.504
Bug fix: adding a client was failing when an apostrophe was used in some of the fields.
Message jobs: viewing message jobs gave a blank screen.
Bug fix: the syncing between users on multiple accounts was being lost and users could not use the Switch feature.
Behaviour: After adding an appointment with the Double-Book checkbox ticked, the checkbox is now automatically cleared for the next appointment. This forces users to explicitly pick double-book each time.
