Create shotcode gallery in root themes 2.3.0 and bootstrap 2

i want to create short code gallery in this template, but this shortcode can not be run, can you help me please?

Just to be clear, are you using Roots 2.3.0 or Bootstrap 2.3.0?

Roots 2.3.0 is 3 years old and it’s not something I think anyone will be able to assist with here.
