I have several feeds from an iCloud account, containing ~10 calendars, that I pull into site using AI1EC. These work OK generally.

Occasionally, I need to refresh the feed manually to get an iCal event up there immediately. When I refresh the feed, it may refresh. Quite often however, I get two other scenarios:

a) When refreshing, I get the alert as follows:
A system error has prevented calendar data from being fetched. Something is preventing the plugin from functioning correctly. This message should provide a clue: transfer closed with 64194 bytes remaining to read

b) The refresh process seems to hang for a while then i get an error such as:

All-in-One Event Calendar has been disabled due to an error:
Argument 1 passed to Ai1ec_Ics_Import_Export_Engine::_is_timeless() must be an array, null given, called in /home/sites/rathfern.lewisham.sch.uk/public_html/wp-content/plugins/all-in-one-event-calendar/lib/import-export/ics.php on line 258 and defined

Which in turn disables the plugin completely.

What might be causing a) and b) and what can I do to prevent this happening?

Hi,

All of the feeds are mapped to a single Event category in AI1EC and configured as follows:

Event categories: My Category Here
Allow comments: No
Show map: Yes
Keep original events categories and tags: Yes
On refresh, preserve previously imported events that are missing from the feed: No
Assign default time zone to events in UTC: Yes

Any suggestions?

NB: I get these feed addresses by logging in to iCloud.com, going to calendar, then click on the sharing/broadcasting icon to the right of each calendar (Calendar Sharing) then copying the address under the (ticked) Public Sharing heading. Is that right?

I was able to import events from all the above feed URL’s. How much PHP memory is available to WP? You may need to use a plugin like WP-Memory-Usage (see https://www.ads-software.com/plugins/wp-memory-usage/ ) to get this info.

OK. tired that plugin and get the following:
PHP Version : 5.3.28 / 64Bit OS
Memory limit : 512 MB
Memory usage : 142.4 MB (28%)

The usage value doesn’t seem to change when I hit refresh on one of the feeds. Might other plugins be interfering with the refresh?

Please install Advanced Cron Manager plugin and see what tasks are queued to run. It may be that a task is stuck. The task that updates the feeds in Ai1ec is called ai1ec_cron.

I’ve added Advance Cron manager and don’t see that a1ec_cron task listed.

This is what i get listed. Not showing in BackUp Buddy Server Tools WordPress Schedules (Cron) either.

Any suggestions as to why it’s not listed?

Hi,

If you do not see a1ec_cron task, it would be best to reinstall the plugin using the manual upgrade process: https://time.ly/document/user-guide/troubleshooting/perform-manual-upgrade/

Do not forget to back up all your data before reinstallation.

I’ve done a manual reinstall of the plugin and still do not see the ai1ec_cron task. Any other suggestions, or what is my next step?

I’ve noticed that when I have refreshed the feeds from iCloud/iCal, when I view ‘All Events’ the recently added events to iCloud are being imported but DO NOT have any event time/date assigned, which improbably why they are not displaying. Have you encountered this before?

Additionally, When I try to me these events without date/time to the bin, I get an ‘Error moving to bin’ alert.

UPDATE: I’ve taken a copy of the site to localhost MAMP. Deactivated all plugins except AI1EC. Deleted all feeds then added single feed (webcal://p26-calendars.icloud.com/published/2/-O0Ir0tja5_BBIWN2VBC-38pau4w1dI70TZKUvKMNtacXF0KL-JzE8hSjzsfmr1uFzqBCWrXo0OKU2CC7d2oxLxKb_DDtD8XK_vJy2eDjUk) with default options. Shows 22 events imported, and listed in All Events.

But none have a date time entry in the date/time column of All Events. When I examine each event it populates the event date/time fields with the date/time at that point when you hit edit!

If you exit the edit event without updating, it still doesn’t show on the calendar, but if you hit update, the event now has a time/date and will show on the calendar. But this is not the way we want to use the plugin!

Incidentally, when I activate the Advanced Cron manager I can now see ai1ec_cron at the top of the list. But when I execute it, the events still don’t have date/times assigned.

Have you got any further suggestions? This used to work!

Can you confirm/clrify your recommended method for obtaining the .ics url from iCloud please too.

UPDATE: This whole issue is as a result of the WP 4.4 update conflicting with AI1EC.

See this thread here for the solution.
