EE version
Calendar version 2.0.4
MER Version 1.0.4

Our event calendar stops showing on our site when I activate MER.
Any insight in how to correct this?

Hi Bill,

This sounds like the server is running low on memory, or there are too many queries on the calendar page. Can you try setting the calendar to not show expired events?

[ESPRESSO_CALENDAR show_expired=”false”]

Hi Josh,
It is already set as you suggest. We have both the calendar and and event_list on the category pages to accommodate different customer preferences. Both work fine until I activate MER. The event_list still shows after. Server utilization doesn’t indicate any issues. Can you advise why MER would impact memory until a registration action was taken? I’ll look for other impacts based on feedback.

Here are the short codes I have on the category pages:
[ESPRESSO_CALENDAR event_category_id=”canvas” show_expired=”false”]
[EVENT_LIST category_identifier=”canvas” show_expired=”false” order_by=date(start_date),registration_endT show_recurrence=false]

When Multi Event Registration is activated, it requires more memory than when it’s not activated. If you have a large number of events, the number of queries on the event list/calendar page will increase significantly with each feature activated as well (especially if the calendar and event list are on the same page).

As an example, I have a test site with 49 active events set up. I’m using the featured thumbnail and add to ical features, and the event list page without Multi Event Registration active reports it did 357 queries in 0.712 seconds, using 3.90MB memory. With Multi Event Registration active, it reports it did 405 queries in 0.710 seconds, using 3.93MB memory.

So I’d recommend any/some/all of these ideas: You could try splitting off the calendar from the event list page, or limit the amount of active events, or increase the amount of memory/allowed queries.

Interesting. I will do some testing tonight after “customer hours” and get back with you. Thanks Josh.
