comments not showing

Do you have any cache installed? If so, have you checked the cache plugin to serve fresh version to visitors when post new comments?

on posts are working. Can comments be posted on custom page?

Theme Options > General > Comments on pages > On

Tnx Alx! That was a problem! Excuse me! I did not saw that!
