{{cs1}} and {{cs2}} templates report this error when one parameter has text that looks like it is a parameter missing a pipe (<code>|</code>). 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: {{tag|nowiki|content={{=}}}}.  For most other cases, simply add the missing pipe.
