That mod looks like it needs 3 postbit hooks-
postbit_start
postbit_messagearea_start
postbit_end
For start and end just paste this at the very top (and the other at the very bottom) of the postbit_simple_bop5_vb4 template.
Code:
{vb:raw template_hook.postbit_start}
Code:
{vb:raw template_hook.postbit_end}
Then paste this code
Code:
{vb:raw template_hook.postbit_messagearea_start}
right above this line in the existing template:
Code:
<vb:if condition="$post['title'] OR $show['messageicon']">
I guess I will add these hooks back in in the next update with on/off options for each.
