Translation doesn´t work

Hello there, since yesterday I´m trying to get
the translation to work. I just want to
read WDTFS on lezhin.com but nothing really works.
I have no idea about this overtooning-stuff.

I´m using a desktop Pc with Firefox 40.0.2. I´ve
tried both methods: Add-on AND bookmark.
Bookmark didn´t work. Add-on only translated
the head of the webside.  
Furthermore I´ve tried this with Chrome at desktop
AND laptop, didn´t work neither.

Screenshot webside:

Hope someone can help me soon.
Greetings from Europe.

Hello MsAmina, fellow european,

I detect from your second screenshot that no webtoon was registered by the script as scanlated.

And strangely, per your claim, it happens with at least two different browsers.

I need you to access the console of your browsers (whichever you prefer):
- in Firefox, open the Menu and go to "Development Bar" (or push SHIFT + F2 on your keyboard). If you don't see a big window open, then maybe a very little one horizontal bar popped at the bottom, and you need to click on the wrench. Once the development bar has popped up, go to the console tab
- in Chrome, Menu > More tools > Development tools > Console tab

Once you are in the console tab, type in (with care, but autocompletion should help you):

localStorage.getItem('overloaderData')

And please copy paste the result here.

You can try an hypothetical fix by yourself, typing

localStorage.removeItem('overloaderData')

and then retrying.

If the fix doesn't work, please also give me the link to the tutorial you used in order to install/use the addon/bookmark overtooning. Maybe it isn't using my own files.


edit:
Also, tell me if you see "{}" when accessing http://feed.bumblebits.net/

I´m using Firefox - Chrome was just trying.

Okay, here is the screenshot for the browser console:
(I think the hypothetical fix didn´t chance anything xD)

I can see "{}".

And this is the tutorial I used:

Thank you for your help so far.

The result from the console looks okay to me.

But there's one thing that bugs me: Lezhin is supposed to be in korean, and "What does the fox say?" is currently up to chapter 24.

Your screenshots show a japanese or chinese version of Lezhin, with chapter only up to 5.

What sorcery is this?

Go in your account (your first screenshot), and switch the language to korean (should be 4th parameter, 2 after your email address, the last parameter in the first pack of 4).

OMG - I´m so stupid (~=__=)~

It´s working. Thank you so much.
Foreign languages for the win! xDD
