Error in index.php file when upgrading to Advance Guestbook

Hi.

When I used the CPANEL script to update Advanced Guestbook to 2.33 it
somehow corrupted the index.php files. I get these errors:

Warning: main(./extension.inc): failed to open stream: No such file or directory in /home/wickham/public_html/guestbook/index.php on line 25

Warning: main(./extension.inc): failed to open stream: No such file or directory in /home/wickham/public_html/guestbook/index.php on line 25

Fatal error: Call to undefined function: session_pagestart() in /home/wickham/public_html/guestbook/index.php on line 31

I find I can run the admin.php file and access the guestbook logs so the database seems OK.

Any ideas how to correct this problem?

(I also posted this message on Carbonize's Forum)

Thanks in advance,

As I said in my forum cPanel has messed up their latest installation files. You need to download the guestbook script from this site then replace ALL your guestbook files EXCEPT admin/config.inc.php.

That solved the problem. Thank you!
