Help:Cite errors/Cite error included ref

Overview
References are defined within  tags.

Issues and resolution
The closing tag is missing or malformed. Ensure that you are either using a closed pair of tags such as content. The last reference on a page will not show this error and will "eat" the following content.

This error will also show if  tags or a named reference are nested inside another set of  tags.  tags cannot be nested; see WQ:REFNEST for details.

Bugs

 * : Misleading error message for omitted s

Improperly closed ref tag
In this example, reference 2 is improperly closed with. Note how the content between the reference 2 and the reference 3 is missing:

{{pre2| Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Curabitur pretium tincidunt lacus. Nulla gravida orci a odio. Nullam varius, turpis et commodo pharetra, est eros bibendum elit, nec luctus magna felis sollicitudin mauris. Integer in mauris eu nibh euismod gravida.

Nesting ref tags
Here reference 2 is nested inside reference 1:

{{pre2| Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.
