Could you try rebuilding NodeBB? Perhaps something happend with just this step and redoing it will fix the forum. If this doesn't work, then reinstallation will probably be required (or at least the easiest way).

Hi. Sorry for my bad english. I installed Nodebb, I really liked the forum. I think Nodebb is the best forum in the world. But 1 big drawback upset me. I did not find a solution how to enable transliteration cyrillic urls. It is very important in terms of seo. For example: Now i have links as /topic/1/заработок-в-интернете I need /topic/1/zarabotok-v-internete
