Can't open lrf format with

[prom king]

Recently I updated Calibre to newest version and now when I convert ebooks to lrf format I can't open them in calibre e-book viewer.

For every e-book I try to open I first get an error message that says:

calibre, version 4.14.0
ERROR: Unhandled error: Uncaught TypeError: Cannot read property 'is_html' of undefined<br><span style="font-size:smaller">Error at userscript:viewer.js:37212:23</span>

Traceback (most recent call last):

TypeError: Cannot read property 'is_html' of undefined

And then it is loading forever. While on older version I could open lrf ebooks, to check how they are converted before I put them on my Sony PRS 500

I see the same error trying to view LRF with the Calibre viewer using 4.14.

note you will need to clear the viewer's cache for the fix to work.

Great, kovidgoyal, but what do I do with that piece of code? I do see people exchanging code on github but I never see instructions of what to do with that code.

I am little bit in programming and I presume that code was written in java?

You just have to wait until the next version of Calibre is released and your problem will be solved.

What, you can't tell me how to paste that code into the program? I tried opening ebook-viewer.exe with Notepad++ but all I get is a display of some strange characters.

You are running a compiled version of Calibre. So you'll have to wait for the next version to be released.

To use the code snippets, you will need to be running calibre from source. See Setting up a calibre development environment for information on doing this.

@prom king - uninstall 4.14, and install the version you were using before - you won't lose any settings or books.

@prom king For now, don't open with. Just click the LRF format in the formats list and you'll get a viewer that's not the main viewer, but it works well enough.
