[OMP 3.1.2.1] Translation plugin not visible on OMP

Hi,

We’ve installed the translation plugin as seen above on OMP 3.1.2.1, but its not visible on our instaled plugins list. We’ve tried to uninstall and then resinstalling it, however,it didnt solve our issue. Did it happen to anyone else? We need to translate parts of the system to Brazilian Portuguese and it hasn’t been possible so far
