Describe the issue or problem
Im creating a subtheme and work but I get in the names of theme and in administration option a double ## around every text.
Typically that means that there are untranslated strings with the child theme. Please see the post here: OJS 3.3.0-3 hash tags appearing in child theme names - it is suggested to add a .po file to accompany your theme.
I create a subtheme based in default theme. There is already a locale folder with .po files.
Maybe in settings I have to indicate where to find those files?
