We are working on a Bible module and upgraded to v 2.5.6 to get footnotes to appear in the PDF. Footnotes now come through, however we have belatedly noticed that section headings are no longer appearing! It doesn't seem to make any difference whether we use \s or \s1. The only ones that come through are those that we write out in the module.sfm file for missing sections as '\s ***' or '\s1 ***'. (I also tried to download the latest version and try it there but v2.6.7 onwards will not create PDFs at all, giving an error message about '\end' - clearly a different problem. The latest version that works for me is 2.6.6 and in this version I have the same problem - section headings do not display although footnotes do.)
