Hi, for years I have been converting HTML files to produce both AZW3 and EPUB files for two different readers (Kindle Paperwhite & FBReader on Pixel phone) Recently, however, converting the HTML to EPUB produces an empty document. The same file produces AZW3 just fine, so when I convert the AZW3 file to EPUB, it also comes out fine, but the end section is missing. I have attached 4 files. The original HTML file, the empty EPUB, the good AZW3 and the EPUB converted FROM the AZW3 which has the missing end section. I am using portable Calibre 9.16.0 on and an up-to-date Windows 11 machine. The only settings I am changing are device format to Paperwhite 3, linearize tables, no table of contents, and this extra CSS: body {text-align: left;}
p {text-align: left;}
Thanks for your help.
