phpopenchat 3.0.0 problems

[Anonymous]

Someone please put me out of my misery!!

I have installed phpopenchat and keep getting an error:

Sorry, an error occurred.

[2] session_start(): Cannot send session cookie - headers already sent by (output started at /home/me/public_html/phpopenchat/config.inc.php:511)

Your webserver has no write permissions in "/home/me/public_html/phpopenchat/tmp"!
Use the Installer to install your chat! Or in your favorite shell, do the following:
chmod 777 /home/me/public_html/phpopenchat/tmp
and press ENTER.

I have just read through 2 years of posts but nothing there has helped!  Don't know enough about php to do any more....

Did you do read the instructions before you pasted them into this forum?

I think this is the salient point:

... in your favorite shell, do the following:
chmod 777 /home/me/public_html/phpopenchat/tmp
and press ENTER.
