Category:CS1 errors: class

It is used to build and maintain lists of pages—primarily for the sake of the lists themselves. They are not part of the knowledge base categorization scheme.

More information:

This category is hidden on its member pages—unless the corresponding user preference is set.
These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

Administrators: Please do not delete this category even if it is empty!
This category may be empty occasionally or even most of the time.

This is a tracking category for {{cite arxiv}} templates that use |class= improperly.

Help desk

|class= ignored

Only used in {{cite arXiv}} templates, |class= is only appropriate when the template uses |arxiv=YYMM.NNNN or |arxiv=YYMM.NNNNN identifier formats; see Cite arXiv §Usage.

To resolve this error, remove |class=.
