I am sure the board has set a Custom Island Insert .
In the post_side.tpl , there do include
Code
{if $smarty.section.post.iteration == 1}
{$island_insert}
{/if}
in the tail.
BUT it just not shown....
It is very strange....

English is not my native language. I try my best to express my thought precisely. I hope you understand what I mean. If any misunderstanding results from culture gaps, I apologize first.
