#19 Warning: sprintf() [function.sprintf]: Too few arguments etc

[barrybristle]

I appear to have correctly configured tsep to index a localhost based project (I needed to apply bug fix 1511191 as described to overcome "Errors on sending headers in PHP") before the index could be properly configured and the database created. However when attempting a run of indexer.php I get warning message:

"Warning: sprintf() [function.sprintf]: Too few arguments in C:\Apache2.2\htdocs\tsep\admin\indexer.php on line 232".
Line 232 is defined as:
"echo "<div class='indexingErrorTitle'>".sprintf( $tsep_lng["error_indexer_is_running"], $lMsg)."</div>\n";"

I regret this is beyond my level of expertise, not being a programmer. Is there an idiot friendly explanation available out there please?
