definitely something broke it. This is the part that takes a bit of time, but you will need to reverse what you did to the point of when things were ok. Looks like something related to your breadcrumbs; are you using something different for breadcrumbs navigation? I noticed it’s in a
tag with an ID of breadcrumbs, and I believe this is the issue.
Not sure if you are aware of this but this theme has pre-coded breadcrumbs ready for you. You just need to install the breadcrumbs NavXT plugin.
