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