PHP Errors

I am trying to clean up PHP errors on our site, and I noticed that there are a lot of them being generated from your plugin.

PHP Warning: Invalid argument supplied for foreach() in /wp-content/plugins/wp-syntax/geshi/geshi.php on line 3388

PHP Warning: Invalid argument supplied for foreach() in /wp-content/plugins/wp-syntax/geshi/geshi.php on line 3429

PHP Warning: array_keys() expects parameter 1 to be array, null given in /wp-content/plugins/wp-syntax/geshi/geshi.php on line 3481

PHP Warning: array_keys() expects parameter 1 to be array, null given in /wp-content/plugins/wp-syntax/geshi/geshi.php on line 2039

PHP Warning: Invalid argument supplied for foreach() in /wp-content/plugins/wp-syntax/geshi/geshi.php on line 2039

PHP Warning: Invalid argument supplied for foreach() in /wp-content/plugins/wp-syntax/geshi/geshi.php on line 2411

PHP Warning: implode() [<a href='function.implode'>function.implode</a>]: Argument must be an array in /wp-content/plugins/wp-syntax/geshi/geshi.php on line 3365

PHP Warning: array_keys() expects parameter 1 to be array, null given in /wp-content/plugins/wp-syntax/geshi/geshi.php on line 3388

PHP is of course very forgiving, so the plugin seems to be working okay. However all of these errors being generated are filling up my error logs, and php runs much slower when dealing with errors such as these.

I would love your attention in getting these issues patched up.

Thanks,
