Not all parameters work with all views. I see you’re using basic view. The monthnav setting only applies to month view.
Is it possible to get a view like ‘basic’ put per month?
Is it possible with Pro?
That’s probably not the most practical because the number of events per month could vary significantly, which would have a huge effect on how long the list is when you jump from month to month.
I would suggest trying the pagination option. It lets you say how many events you want to display per “page” and then adds previous/next links to step through the pages, but since it puts the same number of events on each page, it doesn’t run the risk of blowing up your overall page layout the way a month-by-month list would.
There will be only one (maybe two) events per week. So about 5 per month, that will not be the problem
Pagination is probably still the best way to go. Give that a try and let me know what you think.
