since yesterday I can't really edit my reading list, since every link that utilizes javascript doesn't seem to do anything right now, that means incrementing the chapter numbers, editing the volumes/chapters and ratings, and so on; every other "normal" link I tried still works OK 7344m

Am I the only one with this problem or are there other people like me?
Is it the my fault or is it the website? (I guess it's the website, since javascript seems to still work everywhere else)

I think it's just your problem, for me everything works fine.

You probably need to update your Java, an update came out recently

well, after updating java and disabling noscript it still doesn't work, whereas everywhere else it worked without problems even before that, so I still believe it has something to do with this website

If it works for everyone else, then it can't be a problem with the site

A just ruler amongst tyrants

Ok, first, Java not = Javascript, they have nothing to do with each other.

What browser are you using?

If firefox, press ctrl-maj-j erase the error and go to you list and increment it. Check if some error appear.

I use Firefox and didn't find any errors Spikexp, just 3 warnings on page load, 2 regarding the cursor, the other about IE,
another warning about background-color when clicking in the list to select lines, probably because they usually turn light green, but now nothing happens due to the not working javascript.

I also tried disabling all add-ons without results.

It's really frustrating, since everything worked just 20 hours ago and the only thing that changed were some updates for add-ons and one for shockwave flash...

I fixed the list highlighting-on-click error. Go to one of your list pages and then click refresh in your browser to force it to re- the javascript file that handles lists. Should work after that.

As for the other things you listed that aren't working, your complaint is isolated and I can't reproduce it, so you're kind of out of luck there. It's probably worth trying it in different browser to see if it works there.

Spikexp's instructions are good, you should do this:

1.) open firefox and navigate to one of your lists
2.) type ctrl-shift-j (or in the Tools menu, choose Error Console).
3.) hit the "Clear" button, and make sure "All" is selected
4.) try to increment a chapter number, or do anything that isn't working for you. then check the error console for any new errors.

If you follow those instructions and get errors, post them here. If no errors appear, javascript is either disabled, or not functioning properly in your browser.

Try to delete the cache of your browser.
Like monkey said, it might be that your browser is still using an old javascript (or a corrupt one).

well here goes:

1. Javascript is enabled and works on other websites without fail so far
2. cleared cache(and other stuff like cookies) already several times in the hope of provoking a change without success till now
3. absolutely no errors in the error console when incrementing chapters and so on, only 3 warnings and 3 messages on page load like I already mentioned, here they are exactly:

Also I just had a thought while watching the behavior in my list:

1. changing the priority in the wishlist still works, clicking on the 'Edit' button for an entry works (javascript:editVol(xxxx)), since it opens up the two text boxes to enter volume and chapter numbers, same with opening the text box to add a rating
2. adding a series works too, it just doesn't check for correct spelling like it used to and create links for the correct ones and give warning for incorrect names
3. The 'javascript: doUpdateVol(xxxx)' button doesn't work, same with incrementing, updating the entered rating, adding to a list while in a mangas profile page and incrementing while in a mangas profile page. Loading a profile page gives the same warnings as loading a list page.

So maybe it's just something preventing the clicks from ing, maybe those 2 warnings about cursor are more important than I first thought. I can only guess at the code, so I'm not even really sure, but it's the most likely so far for me. It just doesn't explain the missing correction for 'Add Series'.

seem like the "sendHTTPRequest" that don't work.
EditVol don't use it, but incrementChapter do and doUpdateVol too.

Ok, try this.

Go on your list page.
press ctrl+maj+k

And write this:
sendHTTPRequest(listUpdate, "ajax/list_update.php?s=" + 1802 + "&inc_c="+1);

Replace the 1802 with the ID of one of your manga
you can see it in the url and in the call for javascript function
http://mangaupdates.sitesdebloques.biz/series.html?**id=1802**

After that refresh the page and see if the chapter number have been increment.

using this gives me this error:

Error: sendHTTPRequest is not defined
Source File: javascript:%20sendHTTPRequest(listUpdate,%20"ajax/list_update.php?s="%20+%205920%20+%20"&inc_c="+1);
Line: 1

removing all the spaces doesn't work and doesn't get rid of the first %20 after javascript:

Can you take a screen shot of that, it will be better for me too see it.

No, that's not what I asked for.
press ctrl+maj+k
And write there and tell me what it say.
