# Use of \@argtabularcr doesn't match its definition

I got this error while compiling a document using the IEEEcolor document class from the IEEE Author center:

Use of @argtabularcr doesn't match its definition. \subsection

What should I do to fix this error?

\markboth{IEEE Journal of This and That}%

Removing the \\ from the second \markboth argument fixed the issue
It was a bit tricky to find, since the compiler complained about the error a couple of pages into the document, at the point of the page break where the content of the second \markboth argument was to be used, while the offending command was near the beginning, before \begin{document}.
