All my logs files are always empty

All three log files Access, Error, Server are always empty. Is that an issue or am I missing something.

Sorry about that, there was a glitch with logging for your account -- should be working OK now?

Whoa!!! It is all working now. Thanks a lot.

Excellent, thanks for confirming!

Me too. Can see print() out calls or logging?

Hi there, stderr goes to your error log, but stdout (normal prints) go into the server log...

Hi there! It seems I contracted the same bug when switching to a custom domain name, is there a solution for this?

Ok. I have fixed your account. The issue arises when you move a web app from one account to another.
