148 heluecht 2018-06-19: from my point of view this whole code part is useless.
149 It just renders the body message of technical posts (Like, dislike, ...).
150 But: The body isn't visible at all. So we do this stuff just because we can.
151 Even if these messages were visible, this would only mean that something went wrong.
152 During the further steps of the database restructuring I would like to address this issue.
