Common causes
- A missing
\end{itemize},\end{figure}, or\end{tabular}. - Two environments closed in the wrong order, such as
\end{figure}before\end{center}. - A typo in the
\endname (\end{itemise}after\begin{itemize}).
How to fix it
- Go to the line number in the message and find where that environment should end.
- Add the missing
\end{…}there, or swap the two\endlines into the right order. - TeXpad shows the open environment and offers to insert its
\endin the right place.
