Question

how to remove the activity box(that shows score, rank) which appears in userprofile page(snowflat theme)

Answer 1

1. Edit file qa-theme/SnowFlat/qa-theme.php

2. Add (if it doesn't exist) or merge (if it already exists) this function:

public function initialize() {
    parent::initialize();
    if ($this->template === 'user') {
        unset($this->content['form_activity']);
    }
}
