There has been a critical error on this website.

I went to setting > display. Under LIST-MONTH-DAY disabled new calendar design.

and now on debug I have:

Hi @floraluna
?
I’m happy to report that we’ve recently released an update that should solve one or more issues reported here! Head over to your site and make sure all your event and ticketing plugins are up to date.

Thank you for your patience as we worked through this!

Hi @floraluna

We discover a new issue caused by using the High Performance settings of the REDIS Object Cache Pro plugin. See more on the link below:

https://objectcache.pro/docs/configuration/#high-performance

If you are still having issues after updating the plugins, as a workaround, try removing the following settings and it should work as expected:

‘compression’ => ‘zstd’,
‘serializer’ => ‘igbinary’,

We have an internal ticket to address this (TEC-4379). We don’t have a time estimate to share at the moment, but once there is an update, we’ll be sure to let you know.

Best,
Rob

same issue, following

Hi @floraluna and @kgw203,

Please add the following code to your wp-config.php file:

define('WP_REDIS_CONFIG', [
    'compression' => 'none', 
]);
define('WP_REDIS_CONFIG', [
    'serializer' => 'php', 
]);

This should correct the issue until a more permanent solution is in place.

Thank you,
Erica

This didn’t work for me.

Also turning off our compressing/cacheing isn’t a good fix for the issue. Please let me know when the issue has been fixed. I’d rather not migrate to a different plugin solution for my events and tickets.

Thanks

Hi @kgw203,

Thanks for getting back to us. Sorry to hear about this. Appreciate you checking on your end as well and notifying us. Rest assured that this has been on our radar.

I’m curious, could you try this configuration here and see if that makes a difference?

if( ! defined( WP_REDIS_CONFIG ) ) {
	define('WP_REDIS_CONFIG', [
		'compression' => 'none',
		'serializer' => 'php'
	]);
}

if( ! defined( WP_REDIS_DISABLED ) ) {
	define('WP_REDIS_DISABLED', getenv('WP_REDIS_DISABLED') ?: false);
}

Let me know how it goes.

Best,
Abz

this didn’t seem to help either. the event pages still have major errors

but I’m not really looking for a solution that turns off redis compression.

any idea on a timeline for a fix for this? I’d rather not migrate to a different plugin solution for my events and tickets.

thanks

are there suggested versions of The Events Calendar, Events Tickets and Event Tickets Plus to rollback to in order to avoid this issue until it is fixed?

As of now, there’s no other workaround other than the configuration. https://objectcache.pro/docs/configuration/#high-performance

‘compression’ => ‘zstd’,
‘serializer’ => ‘igbinary’,

Reverting to the previous versions of the plugins would not also help.

Next Steps

I’d encourage you to open a Support Ticket on our Help Desk. It would also be great if you could copy and paste your System Information on the helpdesk ticket as well. We would like to investigate further of this issue.

Lastly, rest assured that this is on our radar. However, we would not hold you if things are not working anymore on your end. We will be glad to refund you within 30 days of payment, whether initial payment or renewal — see our refund policy here — https://theeventscalendar.com/knowledgebase/k/refund-policy/.

We’re looking forward to help you with this one.

Best,
Abz

Hi there,

We’re back with good news for you.

Our developers fixed the issue between the Events Calendar and Object Cache!

Please update your Events Calendar plugin to version 6.0.3.1 to apply those fixes to your site.

Hi @floraluna,

We haven’t heard from you in a while, so I’m going to mark this as resolved. Feel free to start a new thread if you have any more questions.

Best,
Abz

@gugaalves is there a patch that can be applied to a pre 6.0 version? Thanks!
