If a theorytab title has a bracket, editing the theorytab will put me to a 404 page

If you edit this theorytab what will happen is it will send you to https://www.hooktheory.com/theorytab/view/smash-mouth/all-star-(negative-harmony-version) so I get rickrolled instead of getting sent to the theorytab

Thanks for the report. We’ll take a look and catch disallow these nonstandard chars so the crash doesn’t happen

@dave so it’s still not fixed

This loads for me:

@dave I edited a different theorytab that also had a bracket and the same thing happened there

@dave you haven’t fixed it

@dave that link is actually https://www.hooktheory.com/theorytab/view/smash-mouth/all-star-%2528negative-harmony-version%2529 but if you edit the theorytab it sends you to https://www.hooktheory.com/theorytab/view/smash-mouth/all-star-%28negative-harmony-version%29

@dave why haven’t you fixed it yet

if you edit https://www.hooktheory.com/theorytab/view/smash-mouth/all-star-%2528negative-harmony-version%2529 it sends you to https://www.hooktheory.com/theorytab/view/smash-mouth/all-star-%28negative-harmony-version%29


Sorry this thread (and others related to the song db) have taken a back seat. I tried some of the above links but none work. Is it possible that the old version with the bad character in the URL was deleted?

The only ‘negative harmony’ version of All Star I can find is at this URL, and the edit link works.



@chris Yes I changed the name of that one but I still have some more:


Edit the theorytab and save it and it will send you to:


@chris so can you fix it

@Vaz, thank you for the links and for bringing this issue to our attention.

This problem has been fixed. The fix, however, was to fix the original URLs of songs with parenthesis. They were being double URL encoded in a weird way which led to the %2528 in the original URL.

The new URL for this project does not contain the extra %25 wrappers around the parenthesis encoding. Here it is:


Editing it will return you to the same URL, as expected. This URL change will affect all songs that have parens in the artist or song name.
