Illegal string offset 'before_widget' in my_custom_widget_functions.php

We just started receiving these errors. Haven’t changed version of MCW. (Using the latest 2.0.5.)

The front page of our website looks fine, but you can see the error messages when you visit one of the store categories, such as: https://bigbeartools.com/store/#!/~/category/id=6903465

The errors are (making our page look ugly):
