When opening a .epub file, I get many errors like the one shown below printed to the terminal: libepub (II): OEBPS/html/030_c15.html#c15 - No such file Unzipping the .epub file shows that the file 'OEBPS/html/030_c15.html' exists. Is it the anchor (#c15) that is not stripped off? I cannot attach the file .epub file because it is copyright protected. I am happy to send it by separate mail to confirm the error.
Obviously will need a file, i guess you can send it to me, but that doesn't mean i'll fix it, but i can see if it's fixed in something newer than your outdated verison.
I have the file, if someone wants to work on fixing it i can also share it with them.
