In robot_functions.php, find the appropriate $command variable:
Code:
// it can have _PDF or _MSWORD or _MSEXCEL depending on binary
$command = PHPDIG_PARSE_PDF.' '.PHPDIG_OPTION_PDF.' '.$tempfile2;
Change to the following:
Code:
// it can have _PDF or _MSWORD or _MSEXCEL depending on binary
$command = PHPDIG_PARSE_PDF.' '.PHPDIG_OPTION_PDF.' '.$tempfile2.' 2>&1';
And copy-paste what, if anything, is displayed upon reindex.
