[fixed] jevent plugin - jEvents do not show on map

Hello, I have many jevent menu items such as 'search events' as well as 'list eventd by day' etc wich work perfect e.g. when i click an event on the calendar its details are viewable, no prob, it is only when i click on 'event detail' on the map that I receive error 'Sorry - this event cannot be viewed using the link provided.... ' please check here: diveinseas.com/diveinseas/el/2017-02-27-...rm/2017/03/04/-.html
If it is a menu itemid matter. I dont know how to guess the menu itemid of the above link. Please check, thank you in advance

Set any jevents itemid which is not the search or add event menu ones.
To test you can also temprary disable SEF in joomla config.

Itemid value apears clearly in Joomla urls when sef is disabled in Joomla config.

I disabled sef and url re-writting, created all possible jevent menu items (month view, detail view, day list, event list etc ) and changed the item menuid on the plugin to the corresponing one each time, I still receive error 'Sorry - this event cannot be viewed using the link provided'

i wouldn't thought it was an easy one either.
