Linkable categories don't work at some point

Hello everyone,

I was try to implement categories as clickable/linkable in Blog. When user click on category it should show all the blog post under that category. For that I follow this tread and it is working fine at some point. But it doesn't work in some conditions. Like,

Works when;

www.domain.com/global/en/home

www.domain.com/global/en/

If user click on the category link, it takes user to www.domain.com/global/en/categories/category_value

Where categories is the page name and category_value is the category name.

Doesn't work when;

www.domain.com/global/

If user click on the category link, it takes user to www.domain.com/categories/category_value

Which is broken link. 

Please let me know, if someone know how to solve this issue.

Thanks,

Dhaval
