In certain cases, user added as translator cannot edit posts

Overview of the issue

In order to reproduce this issue:

1. You need to be logged-in as a user that is not an administrator.
2. From the back-end, using the admin language switcher, switch to a different language.
3. Visit Posts and attempt to edit the post’s translation by clicking the pencil icon: you will get a link that leads to ###

This is a rare case happening only when certain conditions are met:

• WPML is configured to use the WPML translation editor.
• Then the same setting is reverted to use the native editor.
• There is a user without administrator rights, that has switched the language via the admin language switcher from the back-end.
• This user attempts to edit a post in a secondary language.

Workaround

As a workaround for this issue, follow this steps:

1. Switch to the default language.
2. Go to the original post.
3. Use the pencil icon inside it to go to the translated post.
4. Make your changes and save the translation.

Administrators are not affected by this issue, therefore, they can always translate posts.
