Thank you for your response.

I'm sorry to hear about the challenges in finding older tickets. You can utilize the following method, which is what I typically do:

1. Visit Google.
2. Enter the search query site:wpml.org followed by your search terms.

Regarding the URL detection issue, we can set it aside for the moment, and we will address the "The Advanced Editor jobs synchronization has failed" in this new ticket. https://wpml.org/forums/topic/the-advanced-editor-jobs-synchronization-has-failed-9/

As for this ticket, I will mark it as closed since it pertains to translations not appearing on a page.

Hi Kor, please do not close this ticket, which "pertains to translations not appearing on a page." As you saw for yourself, this problem is ongoing, and we still need a fix.

Thanks for your reply.

Yes, as I've shown you here in this screen recording hidden link , I'm able to make the translated contents show up after clearing the plugin cache. Maybe you can deactivate the cache plugins while you work on the site and reactivate them once you're done editing. I'm looking into your other ticket here now https://wpml.org/forums/topic/the-advanced-editor-jobs-synchronization-has-failed-9/ and will try to follow up on that ticket with you as quickly as possible.

Hi Kor, thanks for your reply. Three things:

1. It looks like WPML 4.6.7 includes fixes for compatibility with the Object Cache Pro plugin, as noted here -- https://wpml.org/changelog/2023/10/wpml-4-6-7-bug-fixes-and-performance-boost/. If you need to deactivate the Object Cache Pro plugin in order for translations to appear, then perhaps WPML a still has a compatibility problem with Object Cache Pro?

2. We are able to recreate the frequent problem where translations fail to appear even with the OCP plugin deactivated.

3. You suggested that "maybe you can deactivate the cache plugins while you work on the site and reactivate them once you're done editing." Unfortunately, it's not feasible for our translators to deactivate plugins while they work and then activate them again when they are done. Our translators are fairly nontechnical people who work across all time zones, and asking them to deactivate and activate plugins could create a large number of problems.

Given that we can recreate the translation sync problem without the OCP plugin, and that WPML is supposed to be compatible with the OCP plugin, what can be done?

Would it help if I show you a video where we recreate the problems while the OCP plugin is deactivated?

Thanks for your reply.

My colleague shared this errata https://wpml.org/errata/object-cache-pro-various-issues/ and this could be a solution to the OCP plugin issue.

Please try the following and see if it helps with the issue:

- Backup the site completely first to prevent any issues.

- Go to /wp-content/ folder on the site and create a folder named mu-plugins if there is not one already.

- Inside the mu-plugins folder create a PHP file with any name ( or wpml-non-persistent-cache.php ) and place the following code on it:

<?php
/**
 * Plugin Name: WPML Non-Persistent Cache
 * Description: A plugin to prevent persistent caching issues (temporary issue: compdev-220).
 * Author: OnTheGoSystems
 * Author URI: https://wpml.org/errata/problems-with-buddypress-multilingual-and-redis-object-cache/
 * Version: 1.0.0
 * Plugin Slug: compdev-220
 */

wp_cache_add_non_persistent_groups( [
		'convert_url',
		'element_translations',
		'get_pages_adjust_ids',
		'get_user_admin_language',
		'translation_priority_relationships',
		'translationmanagement--get_translation_job_id',
		'wpml_cache_terms_per_lang',
		'wpml_endpoints_support',
		'wpml_pre_option_page',
		'wpml_register_string_filter',
		'wpml_register_string_filter--facetwp',
		'wpml_slug_translation_records--post',
		'wpml_slug_translation_records--taxonomy',
		'wpml_st_cache',
		'wpml_term_translation',
		'wpml_tm_blog_translators--has_translators',
		'wpml_wp_cache__group_keys',
] );

We won't be testing option #2 (OCP plugin deactivated) since we have the workaround above. Let me know how it goes.

Thanks, Kor! I had a few problems with this code but it turns out that WPML's email system converted a few parts of your code, so the code that I was copying from the email alert was different from the code that you actually shared.

I still had problems at that point but eventually realized that even with this code, I needed to flush the Redis object cache keys or else the server would still use the existing keys.

Once I did that, almost all of the sync problems stopped. (We're still seeing the sync problem that you split into a separate ticket, so I can reply back to that ticket with more info.)

Now, we're only occasionally seeing the following 504 error message in the browser console as the ATE website loads:

GET hidden link net::ERR_ABORTED 504 (Gateway Timeout)

When this happens, the ATE website (e.ate.wpml.org) loads as a blank page, and it seems that refreshing the browser tab solves the problem most of the time on the first try.

Maybe this is an unrelated issue and maybe the ATE website is having a separate problem today.

So I'll keep an eye on this for a few days to see whether that problem goes away.

But this is already a major improvement over where we were before!

Hi Kor, we're having a lot of trouble with 504 gateway errors now that this new mu-plugin is in place. Sometimes admin-ajax returns a 504 error and blocks us from creating translation jobs, and sometimes the ate.wpml.org website loads and returns a blank screen and 504 error when people are trying to work on a translation.

This was happening a little last week during testing as noted on February 8th, and it's happening a lot now. Not all the time, but often.

So it seems that the mu-plugin has revealed a deeper problem that was obscured by caching earlier.

New threads created by Kor and linked to this one are listed below:
