hey there,
just installed the extension, nice one. then tried to use ".htmlhintrc". anything in it, valid or not, just causes "no problems detected" result.
i was following a video, and the example is a very basic one. create a new html file, use emmet to create basic content, then change some things to cause errors, and try to suppress some in rc file.
i changed closing body tag to bodx, so i now see "tag pair" error. then removed whole title element and see "title needed" error.
then create ".htmlhintrc" file and tried to put {"title-require":false} in it, failed to write and got typo {"tittle-require":false} and voila, the bug.
even tough, i have typo in rc file, suddenly all errors are gone. even after correcting that type, the result was the same: "no problems detected".
I later tried with random test content in rc, even {"a":"a"}, and now i am sure it is not working as desired.
