This is a tracking category for CS1 citations that have parameters without their required pipe.
Citation Style 1 and Citation Style 2 templates report this error when one parameter has text that looks like it is a parameter missing a pipe (|). This error occurs when a template parameter value contains characters and digits followed by an equal sign. If the alphanumeric text immediately preceding the equal sign is a valid CS1|2 parameter name, the module assumes that the template is missing a pipe and emits this error message.
Some legitimate titles will contain a CS1|2 parameter name followed by an equal sign. In that case, enclose the equal sign in nowiki tags, like this: <nowiki>=</nowiki>. For most other cases, simply add the missing pipe.
Pages with this error are automatically placed in Category:CS1 errors: missing pipe.[a]
