but only for that one article? it literaly was just that one article, I use Tiny Tiny RSS and generate a feed (
https://tt-rss.org/wiki/GeneratedFeeds) to send unread articles only, and when I marked the article that I linked as read (meaning it would not sent it to the feed that calibre was accesing), it downloaded everything normal. If you click the link you can see that there's a black square in the middle, I checked the page code and its a dailymotion video that isn't loading, so I'm guessing that's the problem, the question is, how can it be done that calibre when it detects a video in an article either ignores the article or just download everything but ignores the video? again, I have never used the fetch news plugin but it seems I can modify a custom recipe to do weird stuff.
edit: I finally was able to download the article, after searching a lot I found the "print_version()" function, but I needed an url for the print version, and I couldn't find that out, then I stumbled by accident on the "remove_tags" function and at first I thought it was for like tags of the article but it was acctually to clean the HTML of the article, I just told it to delete the part of the article that housed the video (in my case it was <div class="js-dailymotion">) and then it downloaded normally!!
