We just installed HS for it's x.x.x.19 update. The problem is that once we copy our templates to their respective locations (as we've always done), the gary bar between the banner & the breadcumbs does not appear (but used to with x.x.x.18).

The templates are the same that we used with HS x.x.x.18 and they're in the same folders as they always were.

Any ideas on what might have gone wrong?

Just to let anyone know that might be reading, this issue was due to a change to a custom template rather than the update to x.x.x.19 - the gray bar is still present in the standard template.
