This page will help you to fix the cite error message:
A <ref> tag is missing the closing </ref> (see the help page).
- If you have read this help page and find something missing or confusing, please discuss it at the main talk page.

The last reference on a page will not show this error; instead, the code will appear as normal text, <ref>.
Overview
References are defined within <ref>...</ref> tags.
Issues and resolution
The closing </ref> tag is missing or malformed. Ensure that you are either using a closed pair of tags such as <ref>content</ref> or a single tag such as <ref name=refname />.
Extra spaces may also cause this, for example < /ref> or <ref name=foo / >.
This error will also show if <ref>...</ref> tags or a named reference are nested inside another set of <ref>...</ref> tags. <ref>...</ref> tags cannot be nested; see WP:REFNEST for details.
If a reference has not been initiated with a <ref> tag, the error will appear at the properly formed preceding reference. For example, if you code
<ref>reference 1</ref> ... reference 2</ref>
then the error message will appear at the location of reference 1, not reference 2.
When referring to an already named reference, ensure that the ref tag is in the following format. Note the final slash, which must be directly adjacent to the closing angle bracket.
<ref name="reference name" />
See WP:REFNAME for details.

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

Nesting ref tags
Here reference 2 is nested inside reference 1:
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.<ref>Reference 1<ref>Reference 2</ref></ref> Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
