GregOConnor I had a publish issue today and found it to be the date and time when an event is to be open for registration. I set it to open the day prior and all was fine.
Kindly try to update DT version to latest version i.e.4.0 Beta 2 as the same has been released with several bug fixes and improvement so we can see if it helps fixing the relative issues as mentioned
Also, Would suggest to take backup of your site before performing aforesaid steps, in case rollback required whilst facing any issues e.t.c
@gibes-anand You may also try updating to latest version to review for bugs reported if it helps fixing the relative bugs in relation to event management page (front-end)
