the issue could be that the images are hosted in my dropbox folder. i went into the theme and changed every http to an https, as that was the only difference between image urls.
i tested the theme but not before i made the changes, so I'm not sure if that's the problem. try updating anyway.
Why would you choose to get rid of the blue and white theme?
because it's boring as forget.
why do people use (apparently buggy) extensions to change something that was fine the way it was?
just because something is fine to you, that doesn't mean it's fine for everyone else. the saying "if it ain't broken, don't fix it" doesn't apply when you have an old rusty car from the 70's that barely works.
but hey, it still works! so no problem, right?i'm exaggerating here, but my point is that if it can be improved, why not?
EDIT: should probably mention that the buttons don't change on firefox.
