Sorry it´s compatible this format with Amazon E-reades with .mobi extension?

I think it’s actually from the signature HTML, based on this message:

```plaintext
Opening and ending tag mismatch: hr line 0

```

It’s saying there’s an opening `<hr>` tag without a closing `</hr>` tag to match it. Snap.as images should work just fine in the ebooks! Assuming you’re using Markdown to include them, or valid XHTML `<img />` tags.

Right now, we only export .epub files. We might support the .mobi format in the future though.

Hi, was this feature disabled?  
I cannot get it to work.

Not with by blog: [https://write.as/kroeber/.epub](https://write.as/kroeber/.epub)  
Not with the example provided: [https://write.as/blog/.epub](https://write.as/blog/.epub)

It stopped working at least months ago.

@Kroeber I can download the ebook from [my blog](https://journal.paoloamoroso.com) but the generated ePub file doesn’t validate and Google Play Books rejects it with an error. For example, the Draft2Digital ePub validator returns a thick wall of errors:

Hi @ [PaoloAmoroso](https://discuss.write.as/u/PaoloAmoroso)

I can open your downloaded epub file with no issues with Calibre.  
Maybe in Calibre you can then format it in a way Google Books can accept it.

The problem I am facing with [my blog](https://write.as/kroeber/.epub), is that the feature simply does not work. All I see is this:

@Kroeber Thanks for the feedback. I’d prefer downloaded ePub files to validate and open in at least a few major ereading apps and platforms rather than having to edit the files. I confirm the issues with your blog.

I was able to open my blog’s ePub file with [BookFusion](https://bookfusion.com).

The ePub generation feature works remarkably well. Aside from MathJax and the broken rendering of part of a post, all formatting is preserved. I second the feedback of others in this thread about book organization and metadata.

This is disappointing for me. I have subscribed to this feature for years. It stopped working several months ago. And I cannot get support for it. I don’t know what to do.

@Kroeber I’m going to look into the issues you’re having today. Sorry it’s taken so long for me to get to it.

@PaoloAmoroso Besides the first two errors, I’m assuming the other ones are from some custom HTML inserted into one of your posts. The epub format is a little picky, and we simply output whatever custom HTML you might’ve inserted, so that could be the cause here.

@matt I actually don’t remember having ever inserted any HTML in my posts, only Markdown. But my blog does have custom CSS:

```css
article pre code {
    white-space: pre !important;
}
article pre {
    overflow-x: scroll;
}

body footer nav {display:none}

When you open up the ebook, what post shows up as chapter 24? Based on this error:

```nohighlight
[...] section0024.xhtml(38,20): Error while parsing file: attribute "align" not allowed here [...]

```

It seems there might be an element or two with an `align` attribute in that one post (all errors are from `section0024.xhtml`).

I would love to see this feature, as I just had the plan to write a book for myself. When I click on the demo link I only get a literally unhelpful http 500 message. I’d donate if I could see that at least the demo works.

@thaneblack Thx. Converting docs is easy. I use Calibre. I have a cvs file, and manually I can either create an ebook with an ebook software, or create a file that I then convert to .epub using Calibre.  
The point of paying to have this feature was to easily allow visitors to download an epub.

It would be great to know if I can still have that feature or just forget about it and move on with my life. It’s the silence that is becoming deafening.
