Thanks joshcamerote, but the files "create_account.php" and "information.php" are files of OsCommerce.
If I open the file "sts_display_output.php" and add an echo in the line 22 "echo $sts_modules_str.= $sts_mod .' - ';" In catalog i see this:
general.php - general.php - create_account.php - general.php - create_account.php - information.php - general.php - create_account.php - information.php - sts_user_code.php -
it's normal for repeat the same file many times?
