How to format 'Product Review' text box font ?

[akm]

Thanks again for the followup.
Have deleted it several times, and after deleted, the forum webpage displays and works fine.
But, when go to ACP and click on any item, screen goes blank and xthreads_evalcache.php is back.
Delete it again, refresh screen, and ACP comes back to new clicked page, but when click on another item, screen goes blank again, etc. etc.
