Fatal error with most recent update

Also can’t publish new events. I get a “Publishing failed. The response is not a valid JSON response.” error.

Hey @2mooses

Thank you for reaching out.
Yikes! That’s definitely not intended behavior.

The first thing I would recommend is attempting to downgrade to a previous version of the plugin: https://theeventscalendar.com/knowledgebase/k/accessing-older-plugin-versions/

Secondly, I would recommend checking your installation for a couple of things:

1. Are you using a fairly recent version of PHP? Ideally 7.4 and up as per WordPress’ recommendations
2. Are you using a fairly recent version of WordPress? Ideally 5.6 and up
3. What does your PHP memory settings look like? Typically 128MB or higher is a good starting point

If you are unsure where to find that info, head over to Events > Troubleshooting in wp-admin (/wp-admin/edit.php?post_type=tribe_events&page=tec-troubleshooting) and look for the system information section.

Last but not least, it’s a good idea to test for conflicts (preferably on a staging clone of your site): https://theeventscalendar.com/knowledgebase/k/testing-for-conflicts/

Let us know how that goes!

I also ran into the same or similar issue. Had to revert to 5.11.0 to have a usable site again.

Thanks @geoffbel
WordPress version is 5.8.2
PHP is 7.4.25
PHP memory is 512M
I tried disabling all plugins.
I also temporarily borrowed a pro license from another site and installed that.
No luck. Same errors in the log.
Have reverted to previous version 5.11.0 and everything seems ok again.

Hey there @2mooses and @matthewnie

Thank you so much for adding additional info to the mix.
We think that we found the cause of the issue (although we have not been able to reproduce it on our end just yet).

If one of you wouldn’t mind testing a fix, ideally on a staging site (so that your live site is not impacted), that would be awesome.

The fix is to simply add the following filter to your site.
add_filter( 'tec_views_v2_use_subscribe_links', '__return_false' );

This can be done either via your child themes functions.php file OR by using the following plugin.

Let me know if that fixes the issue.

We really appreciate your collaboration.
Geoff

@geoffbel Your fix does not solve it at our site.

Tom

Thank you so much @ssvtom

Back to the drawing board.

Stay tuned!

I just experienced this error after the update to 5.12. I can see the monthly calendar, but if I click any event to see the details, after quite a delay I’m taken to a page that displays the event title along with the message:
“There has been a critical error on this website.
Learn more about troubleshooting WordPress.”

The menu bar and header graphic are also out of wack.

From what I can tell it only appears on the desktop version. The mobile version still seems to work properly.
Noticed that cpanel was reporting cpu usage at 99%

Confirming I have the same issue. Updated to 5.12 and event pages will not load — a long long delay and then finally a 502 error. Reverting back to 5.11 fixed it. I did not see any errors in the error log.

Hi Everyone,

We have a fix for this problem that will come out on a release Early next week.

My expectation is Monday or Tuesday at the latest.

Best Regards,

Hello there @2mooses @lsterling03 @prondeau @ssvtom and @matthewnie !

We just released v5.12.2 that should fix the issue that you’re facing.

Please update and let us know any feedback that you may have.

Cheers,

Thanks @deblynprado
Just updated now, and that seems to have done the trick. No new errors.
