    Strange problem. After upgrading to WordPress 3.5 and Theme Twenty Eleven 1.5. “Read Offline” doesn’t show anylonger on the default Hompage. Neither on the top, nor on the bottom of the post, nor as a widget.

    If I select a post or a page it works well.

        Must have been something odd in the old theme you had. By design, it should only appear on a single post / page. That is, it is working as it should now.

    I have problems when generating mobi and epub files accent. How to fix this problem of language / language?

  3. Hugues

    Awesome plugin, thanks for this! It makes super clear PDF & ePub. I have a suggestion : can you make a PDF clickable table of content please ? (I don’t know if it’s even possible…)

    1. PerS Post author

      Tanks for reminding me, I’ll add it if the library I’m using supports it. I working on the next release, hopefully available next week.

    Hi Per,

    I tried entering this message on your website, but upon clicking the Add Comment button, there was a database connection error showing.

    I love your plug-in. I have one question though, and it might be my permission settings that aren’t right. The icons appear when they feel like it :-). Usually, I have to load a page a couple of times before they become visible.

    I first tried different browsers, but that doesn’t help, so it’s server-based. Then I tried changing permissions (777 on the plug-in dir, 777 on the dirs inside…) on the directories, but that doesn’t do much good either.

    It’s not a big deal of course, but it would be nice of they did appear. I’m running CentOS 6.3 x86_64, PHP 5.4.8, MySQL 5.1.66-cll and Apache 2.2.23. No caches on my Wp installation.

    Hi Per, Great Plugin, works perfectly for me only one thing I cannot get right.
    I use a plugin called formidable to create list questionaires. In a custom display I can filter these questionaires in a certain way. On my site they appear right, The one I filtered. But when I try to make a offline PDF, read-offline picks the first questionaire not the filtered one. Any idea’s what the problem can be?
    Furthermore I am really pleased with it because it’s the first plugin that lets me create good looking pdf’s of tables etc.
    Thanks
    Kind regards Steff

    Per, this is a really terrific plugin for creating ePubs: they pass with flying colours in Sigil. But I do have two questions.

    1. Do you plan to add the facility to generate a Table of Contents in the ePubs and mobis? Otherwise I’ll have to use RO on my XAMPP site to generate the ePubs and then add the TOC manually in Sigil before uploading to the live website for downloading. Obviously, I’d much prefer to automate the process!

    2. I cannot generate valid mobi files at all. I keep getting an “end tag” error. This surprises me because the ePubs are flawless. As things stand, I will have to take the ePub from the above process and run it through Kindle Previewer to generate the mobi for uploading.

    Thanks very much!

    Tim

      Per,

      I have been delving a little deeper into this. I have now found that Read Offline does automatically generate a Table of Contents in ePubs, so long as I use an appropriate plug-in to put the ToC in the post. I have achieved excellent results using Table of Contents Plus. This allows me to put the ToC where I want it in the post, and then Read Offline reproduces it flawlessly in the ePub. Both ToCs even hyperlink to the appropriate points in the main body of text. Even better, I can style the ToC on both the web page and the ePub using CSS. It works perfectly, so there’s absolutely nothing to fix here — thanks!

      Unfortunately, PDFs produced by Read Offline don’t seem to respond to CSS styling. The result is that (a) although PDFs also reproduce the ToC from that inserted by Table of Contents Plus, they include text that I don’t want included here, and (b) as Hugues pointed out above, the ToC in the PDF is not hyperlinked to the text.

      Finally, none of this helps produce workable mobis. At present, I get the following error when I try to generate them:

      I don’t know what this means, but I am sure you do. If I take the ePub generated by Read Offline and convert it manually in Calibre (version 0.9.16), it works perfectly, so I’m sure this can be resolved.

      Many thanks and best wishes,

      Tim

        Tim, thank you for your feedback. I really appreciate it.

        Here’s a teaser. I’m working with PDF at the moment, ePub and mobi next.

    Hi there Per

    Thanks again for this great plugin.

    I was wondering whether you’re still planning on implementing an export to Word option please? If so, I’d be happy to pitch in with some support to speed up development.

    On a separate note, is it possible to add CSS for posts that will change the font and styles and add padding/spacing below paragraphs? I’ve not been able to get that to work but perhaps I’m doing something wrong.

    Thanks again
    Richard

      Export to .docx is on my to-do list. You will also be able to add styles to control the look ‘n feel (not sure yet if you can modify the docx using styles).

      I’ve been rather busy lately, but plan to work on this plugin in the weeks to come.

        hey there!!!

        for a while now we’ve been using this plugin, and boy is it great or what :) since our website is for travelers with limited internet access this plugin really helps us out.

        fiddling around with the settings we noticed you are planning on the docx option. and than we noticed you posted that about a year ago… Hoping you still are aiming at this, because this would help us even more.

        Cheers and keep up this good stuff!

    That’s great news. Thanks Per. Do let me know if I can do anything to help, like beta test for you or contribute in some other way.

    Cheers

    Sorry for yet another comment. Last one for the night… . I’ve just noticed that, if you’re using a password-protected version of a WordPress install, the download links are still accessible to a person not logged in. Do you know whether it’s possible to prevent the download links from being publicly accessible to people who are not logged in and don’t have access to the relevant post?

    Thanks
    Richard

        I use s2member to password-protect my WordPress installation. I have found that adding the following code to the end of my functions.php file deals perfectly with this issue:

        Best wishes,

    This plugin is worth its line in gold. Thank you so much for it!

    My feature request: let the featured image (formerly known as post thumbnail) of a post become the cover image of the export.

    Thank you so much again!

  11. Kathy

    Not sure if this has been added to the wish list. I would like the ability to turn it on and off for different pages/posts. I’ve had to turn it off because there are a few pages that I don’t want it on.
    Thanks

    Hi there, your plugin is a wonderful idea, but the Pdf download produces a Internal Server Error. The other links work like a charme….
    Any thoughts on what the problem might be, or any ideas where to check?

    Cheers Georg

  13. Sue

    Congratulations on an excellent plugin!

    My only request/suggestion would be to either insert the name of the site as “author” or use the name of the poster.

    I’ll definitely be supporting this wonderful WP addition. Bravo!

  14. Helene

    Hi Per,

    Nice plugin, thanks. Would it be possible to have it on forums also? When as widget in the sidebar, it only captures the last post, not the whole page.

    Thanks
    Helene

  15. Vince

    Using Advance Custom Fields for a lot of information on my page, when I use this plugin it only pulls information from the Description field. How do I change it so is uses custom fields too?

  16. Vince

    it appears that there’s no support for page-break-inside as it seems to be ignoring the division and breaking.

  17. Richard

    Hi Per – Hope all is well. Just wondering whether you’re still planning on updating the plugin?
    Cheers

    We have created a WordPress site that embeds interactive charts into the posts using the Visualizer plug (http://wordpress.org/plugins/visualizer/). The plugin uses Google Visualization API to render charts, however, when you save to PDF using your tool, these charts do not show up in the PDF. Is there any way to include these charts in the PDF? We publish research reports and we wanted to automate the PDF output function rather than having to create PDFs of the reports manually. Can you advise?
