Background of the issue:
I am trying to determine if the new version of WPML 4.8 will affect our site regarding changes to Twig templates. I built the website hidden link and do not recall using a Twig template during its development.
Symptoms:
I am unsure if a Twig template was used on our site.
Questions:
Can you verify if a Twig template has been used on our site?
From what I can see in the site's code, you are using a standard language switcher.
You can create a full website backup and then share the credentials in the private fields I am enabling below in case you want me to take a look at this.
Your answer confirms to me, that I did not use a twig template but a standard language switcher. I assume that there is no needed action to be taken in that case.
I will leave it as is, so the WPML update might not impact our site.
