Thank’you, I’ll try writing to them :).

Well, I’ve solved the first part of the problem with a snippet I’ve put in the functions.php file.

Hello,
no, I’m not using any of the plugins you mentioned. And the code has not been changed. I enclose two screenshots with the error I get when I try to download the .mobi file and the .pdf file from my smartphone. The same PC files are downloaded without problems. Thanks a lot.
