When you have follow problem by Click on the Thank-You-Button:

you do not have permission to access this page. This could be due to one of several reasons:

1. Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
2. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

you must change the sid_hide_noaccess-Template:

		<if condition="$vboptions[disable_ajax] != 2 AND $vboptions[sid_hide_ajax_on] == 1">
		<script type="text/javascript">
			if (hide_aktiv) window.clearInterval(hide_aktiv);
			var hide_aktiv = window.setInterval("findposts(fetch_object('posts'),'$hide_call')", 3000);
		</script>
		</if>
		<div id="hide_fieldset"><fieldset>
			<legend><span class="highlight">$vbphrase[sid_hide_post_hide]</span></legend>
			<a href="post_thanks.php?$session[sessionurl]do=post_thanks_add&amp;p=$post[postid]&amp;securitytoken=$bbuserinfo[securitytoken]" id="post_thanks_button_$post[postid]"<if condition="$vboptions[disable_ajax] != 2"> onclick="post_thanks_give_$post[postid](); return false;"</if> style="display:$display_image" rel="nofollow">$hide_img</a>  
		</fieldset></div>
