(Rescan now...)

Empty heading.
The “navigation” role is unnecessary for element “nav”.
The first occurrence of ID “carousel-example-captions” was here.
Attribute “img-responsive"” is not serializable as XML 1.0.

Errors:

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

The “center” element is obsolete. Use CSS instead.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
