says all languages' time limits are 12 seconds; but memory limit is not described.

Did you encounter runtime errors regarding memory limit?
I sometimes find log message limit doing console.log for debug (JavaSpcript case), and when I remove all console.log, the problem disappear.

I am asuming that memory limit for solution is very large (large enough). Isn't this true?

This problem was fixed by a Codewars member: https://github.com/Codewars/codewars.com/issues/1735
Thanks to all who helped me.

Sometimes happens to me too. Weird bug.

I posted an issue on github https://github.com/Codewars/codewars.com/issues/1735
for a slightly old PC has this kind of low resolution monitor.
I hope this problem to be fixed by Codewars; however, any trick to work around this problem is appreciated. Thanks in advance.

Thanks Chrono79!
Changing the browser zoom level worked for me too!
Nice suggestion!

You can try changing the browser zoom level too.

Tested with Firefox & Google Chrome:

When PC (Windows) monitor's resolution is 1280x1024 or 1280x720, within Codewars IDE "ATTEMPT" button cannot be or is hard to be pressed.
This problem occurs when the browser's window is maximized.
The workaround of this problem is not to maximize browser window; howver, if this problem is fixed even when a browser is maximized, it's nice.

Can anybody reproduce this problem?
