Parse error and warning – PHPExec plugin

I’m trying to make use of the PHPExec plugin, but it’s not cooperating. I keep getting this error on the page I’m trying to run it on:


Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/unchaine/public_html/wp-content/themes/Connections2/index.php:4) in /home/unchaine/public_html/wp-content/plugins/phpexec.php(61) : eval()a€?d code on line 3

Fatal error: Call to undefined function: gettotalanswered() in /home/unchaine/public_html/ask/ask.php on line 40

I use WP 1.5 .. if you need it, the url is https://unchained-melody.net/index.php/?page_id=211 . Thank you in advance for any help.. ??
