after adding an entry i get an error and files get deleted

hi there, got the strangest problem here with the advanced guestbook.

I added it to my page and i got i working (i think)

Images are showing and db & tables are set up.

Now when i want to add an entry to the guestbook it does add the entry to my db but then i get the following error

Warning: chdir(): Permission denied (errno 13) in [mydir]/guestbook/lib/add.class.php on line 66

and then (now comes the weirdest part) it deletes all the files that are in the root directory of my guestbook (so it deletes, install.txt, addentry.php, admin.php etc)

I don't think this is normal

Anyone has an idea (i haven't changed anything in the script.

thanx!

oh, by the way.

[mydir] is the address from my root directory. (changed that myself)

Are you on a windows server or linux?

I'm on linux.

(can't figure out why this is happening)

but scince it looks like you have written all of/some of the code it seems like i found the right person! (judging from all the other posts you have answered)

Oh, maybe some more info might help:

server is running apache.

phpinfo:

Virtual Directory Support disabled
PHP API 20020918

I've had this problem myself when I installed server on my laptop running windows. I'll go through the code later to see where it gets the path from.
