Function _load_textdomain_just_in_time was called incorrectly

These PHP notices appear because some of your plugins are not compatible with changes in WordPress 6.7.x. To solve this you can:

• Install all pending updates. The plugin developers may have already provided a fix.
• Disable the output of PHP notices. This either happens because your WordPress is running in debug mode OR your hosting is outputting PHP errors.
• Or downgrade to WordPress 6.2.2 and then wait some time until you go back to 6.7.x until the plugin developers have caught up.
• Or simply wait until the plugin developers make changes in this regard.

Okay, thanks for your quick response. All my plugins and themes are up to date, and WordPress has updated to 6.7.1.

But it is strange that this issue is only affectiing one of my sites All the others are fine.

As I said, its only on my testing site, so it’s not a tragedy. But I would like to find out why it is happening.

Is there anything further I can do?

As described in point 2, it may be due to the PHP messages that are activated. This can vary from project to project. So first check whether the debug mode is activated, see: https://www.ads-software.com/documentation/article/debugging-in-wordpress/

If it is not, at least PHP messages are activated in the hosting. In this case, you should contact your hoster’s support.

Okay, thanks. I’ll investigate that tomorrow.

I had a few minutes, so I checked the debug option.

Debug was activated on the site, so I disabled it. define(‘WP_DEBUG’, false);

Also, no PHP warnings on my hosting sever logs.

Cleared all caches.

No change. The same plugins still won’t load.

Not sure where to go from here.

@bobsled could you please create a ticket on Trac with as many relevant details about your set up as possible so that this can be investigated? Thanks in advance!

Thanks for following up @desrosj

I’ve opened support tickets with the two main plugins that won’t load. Once I get some feedback, I’ll have better information for a Trac ticket. So, I’ll hold off for now.

I have the same problem after upgrading to version 6.7. I had initially solved it, although sometimes the errors would come out but sporadically, by setting the backfront to English instead of Italian which is my language.
After the 6.7.1 update everything got worse, error after error on both the backfront and the site.
In my site there isn’t Woocommerce: https://todabe.it/
