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