Sorry Dr... I forgot a line in the plugin.

The correct code for the plugin is:

if ($vbulletin->options['bop5oldt_en']) 
   { 
      $templater = vB_Template::create('showthread_oldthreadnotice');
      $templater->register('showoldfp',   $showoldfp); 
      $templater->register('showoldlp',   $showoldlp); 
      $templater->register('bop5daysold', $bop5daysold);
      $template_hook[showthread_above_posts] .= $templater->render();     
      $templatevalues['showthread_oldthreadnotice'] = $templater->render(); 
vB_Template::preRegister('SHOWTHREAD', $templatevalues);   
   }

(the line I forgot is in red.)
