Joomla 6.2.0 Language Override Issues — All My Attempts Have Failed

All My Attempts to Resolve This Issue Have Failed

I have tried multiple approaches to resolve inconsistent language override behavior in Joomla 6.2.0, but unfortunately, all my attempts have failed to provide a complete solution.

I am asking Joomla developers and experienced community members for technical assistance. If someone can help, please identify the exact file, class, method, or supported extension point where this issue should be fixed or where a customization can be injected correctly.

I want to implement a reliable solution that works consistently without making unnecessary modifications to Joomla's core files and that remains maintainable after future updates.

Website Background

My website previously worked correctly on Joomla 5. Language overrides were applied without complicated code injections or modifications to Joomla's core.

After upgrading through Joomla 6.1 to Joomla 6.2.0, I began experiencing inconsistent translation behavior in several areas of the website and administrator interface.

The website supports five languages:

Arabic (ar-AA)

English (en-GB)

French (fr-FR)

Russian (ru-RU)

Ukrainian (uk-UA)

I have created the required language overrides for all five languages and checked the relevant override locations for both the Site and Administrator clients.

Despite these steps, some views display the language constant itself instead of the translated text.

For example, a title intended to display as “Technology” may appear as COM_TAGS_TECHNOLOGY rather than being translated into the active language.

Areas Affected

The inconsistent behavior has affected several areas:

Custom field titles: Certain field labels do not consistently resolve to their translated values.

Custom field groups: Some group titles appear as raw language constants instead of translated text.

User groups: Titles based on language constants are not consistently translated in all relevant views.

Tags: Tag titles stored as language constants can appear untranslated in the Administrator list and site-side tag views.

The problem is inconsistent because some field labels and groups translate correctly, while other views display the original constants.

Illustrative Example of the Tag Translation Issue

For clarity, consider a website that uses news-related tags such as technology, world news, business, and sports.

Illustrative custom language constants might look like this:

COM_TAGS_TECHNOLOGY
COM_TAGS_WORLD_NEWS
COM_TAGS_BUSINESS
COM_TAGS_SPORTS

Their language overrides could provide the appropriate translated titles for each supported language.

The issue is that, in certain views, Joomla displays the constant itself rather than resolving it through the active language override.

These examples are illustrative and describe the type of translation problem; they are not claims that these exact constants are built into Joomla core.

Core Files Investigated

I inspected several Joomla 6.2.0 files to determine where the affected titles are retrieved and rendered.

1. Administrator Tag List

File:

administrator/components/com_tags/tmpl/tags/default.php

The original rendering logic displays the stored tag title without explicitly resolving it through Joomla's language API.

I tried changing the output to use:

This modification did not solve the problem in my environment.

2. Site-Side Tag List

Original file:

****components/com_tags/tmpl/tags/default_items.php

I created a template override at:

**templates/cassiopeia_extended/html/com_tags/tags/default_items.php
**
I then attempted to translate the title before rendering it:

**escape(Text::_($item->title)); ?>
**
I also inserted a temporary diagnostic marker to determine whether the override file was being executed. The marker did not appear on the tested page, so I could not confirm that this override was active for that view.

This suggests that the actual rendering path or active layout still needs to be identified.

I understand that Site template overrides do not automatically affect Administrator views, which use their own templates.

3. Other Files Inspected

I also examined:

**administrator/components/com_tags/forms/filter_tags.xml
**
**administrator/components/com_tags/src/Controller/TagsController.php
**
**administrator/components/com_tags/src/Model/TagsModel.php
**
The model retrieves the stored title directly from the database, while the controller uses the language API for its own status messages. These inspections helped me investigate the data flow but did not provide a complete solution.

What I Have Already Checked

I have:

Created language overrides for Arabic, English, French, Russian, and Ukrainian.

Checked the relevant Site and Administrator override locations.

Verified that the required constants exist in the language files.

Inspected the database structure and confirmed that tag titles are stored as language constants.

Investigated the relevant component templates, model, controller, and filter form.

Tried using Text::_() when displaying titles.

Created and tested a template override.

Added a diagnostic marker to determine whether the override was being used.

Despite these efforts, the translation issue remains unresolved.

Request for Assistance from Joomla Developers

I would appreciate specific technical guidance on the following questions:

Is there a known regression or incomplete implementation in Joomla 6.2.0 affecting the resolution of language constants in custom field titles, field groups, user groups, or tag titles?

Which rendering layer should resolve a stored language constant before displaying it?

Are there differences between how Joomla handles language overrides in Site and Administrator views that could explain this behavior?

Is there a recommended plugin, layout override, or other supported extension point that can solve this consistently?

Most importantly, where exactly should the required code be implemented or injected so that it works correctly without repeatedly modifying Joomla core files?

I would be grateful for a concrete file path, class, method, code example, or reference to an existing fix. General suggestions to create language overrides are not sufficient, because the overrides have already been created and checked.

Conclusion

**My website worked correctly on Joomla 5 without complicated code injections. The translation problems appeared after upgrading through Joomla 6.1 to Joomla 6.2.0.

I have spent considerable time investigating the language files, database entries, templates, models, and controllers. I would now appreciate assistance from Joomla developers or experienced contributors in identifying the correct implementation point and determining whether a core fix or a supported extension-based solution is appropriate.**

Thank you for your time and for helping improve Joomla's multilingual support.
