I was also getting the same problem today while seeing codes of others. That's the most sticky problem of SL. I just want to
$("SoloLearn").removeattr(problem of code playground);
Just a single line Jquery. 😢😢😢
Same here. Today I got to coding for the first time on SoloLearn and I got no output on my codes. Bad luck I guess. I eventually thought that the codes were incorrect, being long and complex codes. Then I tried some short, simple ones. Same thing. Then I ran some other folks codes and encountered the same problem. Hope it gets fixed soon. Other than this, SoloLearn rocks!
