Ical and Google Calendar Feed broken in 3.x (latest(

Hi Kevin,

The demo site is working https://wp-event-organiser.com/demo/ (running 3.1.1 also), and there’ve been no recent changes to that functionality so I suspect there isn’t a bug as such.

You’ve already ruled out plug-in/theme compatibility issue, so I think this might be a rewrite issue. Once you’ve upgraded to 3.1.1, try going to Settings > Permalinks and clicking ‘Save Changes’, and see if that solves the issue.

Thanks for the response. I did a rewrite flush (via cli and through permalinks) and no change.

Any other thoughts?

This is a link to a dev site I have to test this https://vzdev.tadpole.cc/calendar/

What if you try yoursite.com?feed=eo-events?

404 errors.

Ok, that’s odd. That would suggest it’s not a rewrite issue.

Without taking the time to investigate the site itself I’m not sure what to suggest. But here’s what I would do:

1. Verify that this line is called: https://github.com/stephenharris/Event-Organiser/blob/3b76c7b3729ad1bd1863ba77d9993e03731c6e0c/includes/event-organiser-register.php#L210 (it’s conditional on a setting, so you may want to check Settings > Event Organiser > General first to ensure that the feed is enabled

2. Then verify it is present in the global $wp_rewrite (after hook init is triggered);

3. Use a rewrite analyser plugin (Monkeyman Rewrite is my personal favourite) to check that the rewrite rule is being added.

4. On template_include filter check the global $wp_query.

5. The last thing you can do is check WP_Query class and try to determine why it’s reach its 404 decision.

I don’t see a 404, actually, it seems like the site starts generating a feed and fails:

That’s the same bug we were seeing on our production site, villagezendo.org, until we rolled back from Event Organiser 3.1.1 to 2.3.17.

Thanks,
Jesse

Jesse,

I don’t think this is the same bug. Your’s might be related to https://www.ads-software.com/support/topic/call-to-a-member-function-format-on-boolean?replies=3 – (though you may have error reporting turned off). In any case, check your error logs and open a new thread if the problem persists.

It’s the same issue – empty square is looking at the same dev site. He just ran a curl on the url, while I let WP handle it. WP returned a page not found for me, but the curl is finding the true error:

PHP Fatal error: Call to a member function format() on boolean in /home/vzendo/public_html/wp-content/plugins/event-organiser/templates/ical.php on line 61

It looks like we are failing on the timezone functions.

FYI – php 5.6.22, apache 2.4.10 and MySQL 5.6 on Debian

Thanks for the clarification, in that case, see the article I linked to above, since I think that might be the cause.
