I'm running an educational forum (https://szkolnecentrum.pl), and, in the first place, I would like to change the names of particular elements. For example, instead of "topic" or "post", I would like to name it "task", "assignment", "answer" or anything like this. More importantly, there is an issue connected to one of the plugins and some part of HTML can be seen in notifications (screen below).

The plugin which is responsible for that error is called nodebb-plugin-question-and-answer-pl (all the plugins don't work except the Chinese one, that's why I would also like to access HTML and try changing it).
