ok , debug is turned on in line 181 of sql_layer.php , just change $sql_debug = 0; to $sql_debug = 1; .... here is what I got ...

SQL query: select radminsuper from nuke_authors where aid='ads'
SQL query: select topicid, topictext from nuke_topics order by topictext

Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in /home/local/public_html/includes/sql_layer.php on line 286

I dont think it helps much though.
