If you need to enable breadcrumbs on full width pages – those pages which have template chosen as “Full Width”, you will need to make a code change. Full width pages are built with segments which span entire browser width instead of being limited to a 960px or a 1140px width grid. While the text content can still limited by the width, the backgrounds can span entire browser width. I did not find breadcrumbs to be very effective in these types of pages, but if you still need to enable them, here is the code change –
Modify the file /template-full-width.php and after the line 19 or so, change the code from –
... id="content" class="">
to
... id="content" class="">
and save. You should now see breadcrumbs displayed on full width pages. You can still disable them on any page by checking the “Disable Breadcrumbs” option for that page (seen below the page/post editor).
