[Resolved] Where or how to translate internal links?

Thank you for contacting WPML support. While you are waiting for one of my colleagues to take this ticket and work on it, let me provide you with first debugging steps or if I can perhaps help with the issue quickly.

We have an article in our docs that explains just that:
https://wpml.org/announcements/2020/02/translating-links-with-advanced-translation-editor/

If that does not help, one of my colleagues will soon come to continue support.

Can you provide examples of these links?

You can also try using the "Translate Link Targets" option in WPML → Settings → Translate Link Targets and check if the links are automatically translated.

Please remember to back up your database before making any changes.

Please show me some examples so I can see the problem and your steps as well. Including examples of these links.

I've enabled debug information for this support ticket. Please see this link for how to get this information from your site and give it to us:

Thank you for the excellent explanation.

I need to request temporary access (wp-admin and FTP) to your site – preferably to a test site where the problem has been replicated if possible – in order to be of better help. You will find the needed fields for this below the comment area when you log in to leave your next reply. The information you will enter is private which means only you and I can see and have access to it.

I noticed that the page translation is incomplete. Please complete it and check if the link is automatically translated.

I mean that the URL will be converted if you translate the page containing this button with the URL. It will be broken if you simply translate the button URL by changing the word in the slug URL. From what I can see, you need to change the slug of the page itself /prix-systeme-dalarme-lanaudiere/.

Here are the steps to follow:

1) Activate the option "Translate (this will include the slug in the translation and not create it automatically from the title)" in WPML → Settings → Translated documents options.

2) Then, edit the /lanaudiere-alarm-system-prices/ page (that you put to the button). Make a minor modification to the page, save it, and navigate to the WPML translation editor. The slug will be added to the translation. Translate or change it and save it.

3) Lastly, update the translated page by making minor modification to the original where you have this button.

I hope this helps.

I am referring to the /acknowledgement/ page (where the button is). You will also need to update the page translation. To update the page translation, modify the original page slightly, save it, navigate to the WPML translation editor, and complete the translation.
