Hello together,

I have a file from 2015, which contains something like this:

\section{title\footnote{ftn-content}}

And the compiled pdf from then show the footnote correct and with the number in order to the other footnotes.

But now I have compiled it again without differences, and the footnote disappears. I have read about this and basically it says that apart from local footnotes its not possible anymore (?) to set footnotes in titles (s.t. the numbers stay in order to all the other footnotes).

What changed since 2015? That is a problem for me because I have to compile a book from then to print it again (with minor other corrections in the text, but nothing in style). How to achieve the same result like back then?

Thank you! Huseyin
