I do believe it is a trivial question. But unfortunately I don't know where I can find an answer.
Where could I find the answer to the following question?
If $S$ is a small category and $X$ is a quasi-topos, is $\operatorname{Fun} (S, X)$ a quasi-topos? If the answer is "no", what would be a nice counterexample? Would it be PsTop?
