subfig package in latex - latex

Question

When I am using subfig package in latex, it gives some errors:
Package subfig Warning: Your document class has a bad definition
of \endfigure, most likely
\let\endfigure=\end#float
which has now been changed to
\def\endfigure{\end#float}
because otherwise subsequent changes to \end#float
(like done by several packages changing float behaviour)
can't take effect on \endfigure.
Please complain to your document class author.
Package subfig Warning: Your document class has a bad definition
of \endtable, most likely
\let\endtable=\end#float
which has now been changed to
\def\endtable{\end#float}
because otherwise subsequent changes to \end#float
(like done by several packages changing float behaviour)
can't take effect on \endtable.
Please complain to your document class author.

How can I solve it?
Thanks and regards!

It looks like a clash between subfig and an old version of the caption package. Try updating your caption package to something more recent. In general, it is a good idea to keep all packages updated to their latest versions.
