Running DT Register 2.7.5 and all of a sudden cannot save events whether creating new events or editing old events. After pressing "save" or "apply" it instantly takes me back to DT Register Conf page.
We found toolbox had a php configuration issue tied to suhosin restrictions which was the source of his problem.
Anyone that ever has a problem that starts "all of a sudden", it's not going to be a DT Register problem. There is no self-destruct code written in so nothing ever just stops working on its own
Gavin - your issue will be resolved after you download 2.7.7 again and reinstall. The initial package had a small issue which was resolved hours later and updated into the package. Thanks!
