This doesn't change breadcrumbURL:

breadcrumbURL.replace("topics/", "");

it returns the string with the replaced text. To update the original, say:

breadcrumbURL = breadcrumbURL.replace("topics/", "");

You're not assigning the result of the replace to anything.

Change...

breadcrumbURL.replace("topics/", "");

To...

breadcrumbURL = breadcrumbURL.replace("topics/", "");

breadcrumbURL = breadcrumbURL.replace("topics/", "");
