Category:Pages using URL template with unknown parameters

{{Unknown params category|URL}}

The most common error in {{tl|URL}} templates is the existence of an equals sign in the URL. To fix this problem, add {{para|1}} before the URL, like this:

{{URL|http://www.example.com/example.aspx?ID=42}} → {{URL|1=http://www.example.com/example.aspx?ID=42}}

Articles in this category may be using {{tl|URL}} or [https://en.wikipedia.org/w/index.php?title=Special:WhatLinksHere/Template:URL&hidelinks=1&hidetrans=1 one of its redirects] instead of {{tl|cite web}} or similar templates.
