I've been following the https://docs.moodle.org/dev/Creating_a_theme_based_on_boost tutorial and have got it all working, even uploading an image and having it appear on the background of the login page.
My issue is when I go to my themes settings page, it is just displaying the language identifiers inside double square brackets like configtitle
See snippet below:
Does anyone have any ideas on why it does this, I've tried searching but haven't got anywhere with finding anything remotely close to this.
In the root of my theme, I have lang/en/theme_photo.php
Any help would be much appreciated.
