Hello!
a problem with a long history, here is it:
Since a long time across multiple calibre versions, I can't convert an ebook to mobipocket - exiting always by the same error : "Error in xpath expression".
I thought I might be lucky because when showing the details I could see an xpath expression. I changed the path to "//*" but that didn't help. Later, I tried the debug option, but the output directory stayed empty except for a text file instructing me about the stages of the conversion process.
Calibre Version: 3.20.0 Win 10 x64
Thank you very much for any help!
