I tried again with the PHP Debugging turned on and got a fatal error:
Fatal error: Smarty: [in db:system_block_online.html line 5]: syntax error: invalid attribute name: 'k.lang_more' (Smarty_Compiler.class.php, line 1334) in /home/tastesof/public_html/xoops/class/smarty/Smarty_Compiler.class.php on line 1824
Since I'm unfamiliar with Smarty and only moderately experienced with PHP, this one is over my head.
