[Resolved] Identifying Twig Template Presence

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client needs to determine if Twig templates are being used on their multiple sites and seeks assistance with the transition for an upcoming Twig template update.
Solution:
If you've added the language switcher through WPML settings, a shortcode, or a widget, rest assured it will continue to function correctly. However, if the switcher is implemented directly in your theme's code, you should consult the theme author to understand how the WPML language switcher is integrated. Alternatively, if you have the necessary skills, you can check the theme's template files yourself to identify the file responsible for rendering the switcher and verify how it has been integrated. It's also crucial to ensure that you have a full website backup for any of your sites as a precaution. For more detailed guidance, you can refer to the following documentation:

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. Should you need further assistance, please open a new support ticket.

Hi there.

Thank you for contacting WPML support.

If you added the language switcher through WPML settings, a shortcode, or a widget, there is no need to worry; it will continue to function correctly.

However, if the switcher is implemented directly in your theme's code, you may want to consult the theme author to understand how the WPML language switcher is integrated. Alternatively, if you have the necessary skills, you can check the theme's template files yourself to identify the file responsible for rendering the switcher and verify how it has been integrated. Inspecting with the tool in the browser won’t indicate whether a Twig template has been used.

One important thing you can do is make sure that you have a full website backup for any of your sites, just to be safe in case something breaks. But not many people reported using Twig.

I hope that you will find this information helpful.

Hi there and welcome back.

We don't have a list of specific steps to follow to find out if your site is using TWIG. Generally, if you believe you haven't used it, you are likely correct—unless a developer has implemented it in a custom manner.

However, you can find a few examples and explanations in the following URLs:

- https://wpml.org/wpml-hook/wpml_language_switcher/
