Thank you for help, problem was very silly – it was dashes 🙂
Sorry for killing your time.
@srobitaille there is launchpad actually =) So WhiteDot – only free theme compatible with last version of LifterLMS.
Btw, if you want only sidebars – its pretty easy to insert they to any theme. There are some helpfull docs on lifter website.
@srobitaille , its WhiteDot theme bug! You can just switch theme and then edit your quiz. I hope whitedot guys will fix this bug soon.
