$post['pagetext'] = $post_temp['message'];
It seems that $post[pagetext] is not the place where my vB reads the post? Or it does overwrite it or something like that...

Edit:

Ok in post[pagetext] is the text of the post - I can read it out, it matches... but when I change it within the plugin the post itself doesn't change - so it seems to me that the forum takes the post text not from this var - but from where?

Maybe showthread.php was modified in 3.5.3.

If you set $post['pagetext'] to some string, then that would indicate if $post['pagetext'] is being used. It would only modify the post that you are viewing page history for.
