i started updating the translation files from teh dashboard 馃槫 The progress spinner ran for ages, then my laptop went to sleep. Since then teh site is stuck on the maintenance message... i have accses to my hosts file manager. Is there smth i can safely remove, and how do i know whether the update itself completed? Id appreciate a short checklist of what to veirfy after its back up. what am i doing wrong??
