404 error on staging site

I have been having the same issue for nearly 40 days. Every morning I open the site and try to click on an individual event post and I get “Opps this page cannot be found” so I have to deactivate and reactivate the plugin. I am running PHP 7.4 as I thought that might be the cause. This all really began with the roll out of TEC 6.0. Any advice on how to avoid having to deactivate, reactivate TEC every morning?

Hi @caffryfrankel @tallydigitalbiz

Thanks for reaching out, and my sincerest apologies for the inconvenience.

Would it be possible for you to set up a staging version of your live site and try to re-do the migration from it? This is to recreate the proper event data and should fix the 404 issues.

Here are the steps to revert and re-do the migration:

1. Update to the latest versions of The Events Calendar and Events Calendar Pro.
2. Remove any un-needed draft events and empty the Trash.
3. Install and activate the Code Snippets plugin.
4. Add this snippet and run it once (be sure it does not stay activated).
5. Go to Events > Settings > Upgrades and go through the migration process again.

Please re-do the migration on your staging site.

Let me know how it goes.

Thanks for your answer. I followed your instructions (deleted any old or draft events and redid the migration) on my staging site and it still is giving me a 404 error when I try to view the actual single event pages.

Any other thoughts?

Hi @caffryfrankel

Could you try editing the event that has the issue, change the date to a new one, save it, and check if that makes a difference?

Moreover, please provide the version of the following. This will help me understand how your system is set up.

• PHP
• WordPress
• The Events Calendar
• Theme

Thanks for getting back to me.

Changing the date did not help.

On the staging site, here is the system info

PHP version 7.4.16?
WordPress version 6.1.1
The Events Calendar version 6.0.9
Theme is a child’s theme possibly of Twenty Twelve

Hi @caffryfrankel

May I ask for the version of The Events Calendar that you’re using on your live site? In addition, could you also provide the direct URL (from your staging) of one of the events that is showing 404 error? I’d like to check it further on my end.

Moreover, please also provide the values of the following (from your staging):

• Custom Tables Migration Status
• Custom Tables Health Check

You can find the values by navigating to Events > Troubleshooting.

Looking forward to your reply.

The Events Calendar on Live site is here: Version 5.16.4 |
Staging site is here: https://www.hillstead.org/1676498327036/
404 error shows here on these single event pages: https://www.hillstead.org/1676498327036/event/the-art-of-shearing/
https://www.hillstead.org/1676498327036/event/gala-2023/
https://www.hillstead.org/1676498327036/?post_type=tribe_events&p=24768&preview=true

I don’t understand how to get the Custom Tables values. There doesn’t seem to be any information on the troubleshooting page. but the Upgrade tab in settings says teh Migration is complete and lets me click on the events and get to the Edit Event page. But will not let me view it. Can you please let me know how to do this?

Hi @caffryfrankel

If you’re using The Events Calendar 6.0.9, the the Custom Table values from the Troubleshooting page should be available.

See- https://share.getcloudapp.com/YEueGKWY

If you still could not see the values, I suggest re-doing the migration again.

Could you try activating only our plugins and use a basic theme (e.g. 2020 theme), and check if that makes a difference?

Moreover, please provide the URL of your calendars page (in staging), and the name of your hosting provider.

Looking forward to your response.

Hi @caffryfrankel

I hope you are well. I wanted to follow up about the issue you encountered.

Are you still experiencing the 404 error after migrating your events to the new Event Data System?

Thanks for getting back to me. I deactivated everything and still getting the error on single event pages.

Custom Tables values as follows:
Custom Tables Migration StatusCompleted
Custom Tables Health CheckGood!

My calendar listings page won’t show on the staging site. It should be https://www.hillstead.org/1676498327036/calendar but it redirects to an image on the live site (https://www.hillstead.org/wp-content/uploads/2015/02/calendar.jpg).

Hi @caffryfrankel

Thanks for your response and for providing additional details.

Could you try activating only our plugins and use a basic theme (e.g. 2020 theme), and check if that makes a difference?

If that doesn’t help, please try to empty the additional content from Events > Settings > Display, and check if that helps.

Let me know how it goes.

Thanks again. I tried all of this and had no luck. Still 404 on individual pages and calendar listing sending me to an image on the live page.

I really would like to update to the latest version of The Events Calendar, but I can’t do it until I know it isn’t going to break my site.

Hi @caffryfrankel

You could try creating a staging version of your live site using the WP Staging plugin and update The Events Calendar from there, and check if that resolves the issue.

Let me know how it goes.

This is exactly what I am doing—using WP staging. And no luck.

Hi @caffryfrankel

Just to confirm, you tried using a fresh copy of twenty-twenty theme and the issue persists? I am just making sure that there are no customizations running in the background.

From your staging site, could you try adding this snippet code, flush your permalinks again, and check if that helps?

<?php

/*
 * Possible solution for Single Event page 404 errors where the WP_Query has an attachment set
 * IMPORTANT: Flush permalinks after pasting this code: https://tri.be/support/documentation/troubleshooting-404-errors/
 * Updated to work with post 3.10 versions
 */
function tribe_attachment_404_fix () {
	if (class_exists('Tribe__Events__Main')) {
		remove_action( 'init', array( Tribe__Events__Main::instance(), 'init' ), 10 );
		add_action( 'init', array( Tribe__Events__Main::instance(), 'init' ), 1 );
	}
}

add_action( 'after_setup_theme', 'tribe_attachment_404_fix' );
