Today this question came up where the OP wanted to use jtab in his post, but it wasn't rending even though the website for jtab showed it working. It took a lot of trial and error from me and the OP to actually get it in a good state as seen in the edit history which for some reason had a problem with the Dsus2 chord and some spaceing.

A formatting sandbox on the meta would prevent someone having to edit their question multiple times on the main site due to a rendering error on our side and even more so since we can't render it in a preview yet.

    We now have a sandbox. Please use it for testing out posting either jtab or abcjs.

I am also having that problem in Fighting against the F Chord

This is supposed to be rendering an F chord and a Bm7b5 chord as shown on http://jtab.tardate.com but no joy:


In the short term, if anyone can show me what I'm doing wrong, I would greatly appreciate it.


  • They all display now. There was an extra slash in both. Double check the fingerings/notes are what you want on your post I think I screwed up the F chord.

  • @Dom I'm terribly sorry but I screwed it up again and I don't see any history on the deleted post so I can see how you fixed it again.

  • Now it shows. And I have the history as well. Maddening. Must have been a Chrome glitch.
