Node translate tab access Why translate tab only available for super Admin in node &amp; taxonomy form.
how can i view this tab &amp; also button of save &amp; translate for both Node &amp; Taxonomy
to another roles (Editors &amp; Translators), what is the proper permission access
should be given to show the translation tab ?

Forget to mention, this happen only when the node or content is unpublished,
but if its published the tabs appear normally.
I think it's because the not-super-admin users don't have permission to edit unpublished content that they didn't create.

If you want to alter this behavior you can add a new permission "edit any unpublished content" and use hook_node_access to allow editing unpublished nodes (if they have that permission)
