[Plugin: Event Organiser] Unable to save venue details

Hi David
This is known issue that affects a minority of people. The next major update (1.4) will render resolve the bug, but it is immediately fixable. See this thread: https://www.harriswebsolutions.co.uk/event-organiser/forums/topic/events-organiser-not-saving-venues-parameters/

Fixed in 1.4. Though there is a minor bug where an error message appears after creating a venue. The venue is successfully created, and this second minor bug will be fixed in 1.4.2
