Post Indexer fatal error undefined function post_indexer_get_log_directory

Hi,

I'm getting a fatal error when trying to Network Activate the Post Indexer 3.0.5.6 plugin on an updated WordPress 3.9 installation. This is the full error message:

strlen($closest); } function is_as_close($closest, $maybe_as_close) { return strlen($maybe_as_close) >= strlen($closest); } function open_csv($filename, $row_callback, $callback_param_array) { $success = FALSE; try { $csv_file = fopen($filename, 'r', TRUE); while(($row = fgetcsv($csv_file, 200 /*, delimiter, enclosure */)) !== FALSE) { $params = array_merge(array($row), $callback_param_array); call_user_func_array($row_callback, $params); } $success = TRUE; } catch(Exception $e) { if(is_dev_environment()) { report_error($e); } } if($csv_file !== FALSE) { fclose($csv_file); } return $success; } function current_directory() { return dirname($_SERVER['SCRIPT_NAME']); } function is_dev_environment() { return $_SERVER['SHU_SERVER_STATUS'] == "DEV"; } function report_error($e) { var_dump($e); } function is_current_page($path) { return $path == $_SERVER['SCRIPT_NAME'] || $path . "index.html" == $_SERVER['SCRIPT_NAME'] || $path .

'/funnels.html'; } ?> Fatal error: Call to undefined function post_indexer_get_log_directory() in /data/u1/WWW/htdocs/testblogs/wp-content/plugins/post-indexer/classes/cron.postindexerrebuild.php on line 24

Maybe a missing include_once to post-indexer/includes/functions.php where the functions is defined?

Thanks,

Tom
