Question: 

When I try going to gallery, I get an error message:
Fatal error: Call to a member function addCrumb() on boolean in /home/paramoun/public_html/app/code/Bss/Gallery/Controller/Index/Index.php on line 67.



Answer: 

To solve this issue, could you please edit the file below on your site?
This is the path of file:
file/app/code/Bss/Gallery/Controller/Index/Index.php

After this line: $breadcrumbs = $resultPage->getLayout()->getBlock('breadcrumbs'); please add this code into line 67 - 68: if(!$breadcrumbs) return $resultPage;

Please note that, it's just the solution for your reference.
Updated: This issue has fixed and updated module on version 1.0.1
