PHP Fatal error: Uncaught Error: Class “WC_Settings_Page” not found

I’m not able to reproduce the issue on my test site. I’m going to look into this. Can you please send your Site Health info (“Copy site info to clipboard”) to [email protected]?

We are having the same issues. Was causing critical error screens to come up when in the backend of the website.

We have deleted the plugin, and issue seems to be resolved.

Interesting. This might be an issue with WP Engine. I notice both of you are using it.

Here are some people talking about something that looks like the same issue:

https://forum.bricksbuilder.io/t/wait-wp-list-table-error-on-wpengine/21201

Can either of you post the exact code on line 121 of wp-includes/plugin.php on your server? I’m wondering if there’s some sort of modification to that file, because that line should not be triggering the autoloader.

@tharmann: When you get a chance, send me the Site Health info. I want to see if there’s anything else in common between your site and bobconan’s.

Sure thing, here’s line 121 of wp-includes/plugin.php:

function add_filter( $hook_name, $callback, $priority = 10, $accepted_args = 1 ) {

And I’ll send over the site health info straight away.

Thanks!

I’d like to add something that may help on your end as well: we have 3 sites running your plugin and all 3 are on WP Engine. Only 2 of the 3 are experiencing the fatal error issue. Those 2 are both on version 2.8.2 of your plugin and 8.7.0 of WooCommerce. The 1 that isn’t experiencing the fatal error is on version 2.8.1 of your plugin and 8.6.1 of WooCommerce.

All 3 are running version version 6.4.3 of WordPress. Hope this helps!

I can’t figure out why this is happening, but I think I can fix it anyway.

Try the development version I just uploaded (trunk):

https://downloads.www.ads-software.com/plugin/woo-mp.zip

That’s a direct download link.

Let me know if that fixes the issue for you without disabling the settings page.

@tharmann: Have you had a chance to try out the patched version yet?

@bobconan: Would you be able to try out the patched version?

Hi there, for what it’s worth, we were also experiencing the same errors on our WP Engine sites. In addition to the error message we were also experiencing a lot of issues with resource usage. This patched version appears to have fixed this issue for us. Thanks!

@kylelarkin, thank you for confirming that. I’ll include this change in the next version of the plugin.

@bfl The issue is not specific to WPEngine. It’s occurring on Pantheon as well. Both hosts support git based deployments. I’ve seen similar issues occur when a file is mistakingly ignored by git. I’m testing the patch you posted on a Pantheon deployed site now.

UPDATE: Confirmed that the patched version works on Pantheon when deployed via Git.

@dswebsme, thanks for confirming on Pantheon. I’m not sure what the issue is, but it doesn’t seem to be caused by a missing file.
