And now I get errors, like i had before I guess, but I still get errors. I installed everything properly, and idk why I get these errors..

on login screen:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/enrit/public_html/include/constants.php:94) in /home/enrit/public_html/include/session.php on line 46

and on registering screen:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/enrit/public_html/include/constants.php:94) in /home/enrit/public_html/include/session.php on line 46

Heres the place..

PLEASE HELP!!!!!

If i can get this log-in and register system up, its just one more thing done for doing the TEXT rpg im working on! This is probably gonna be one of the harder things, so PLEASE HELP!

The "Headers already sent" error means that you are attempting to send a Header after some HTML is already sent to the client.

It doesn't need to be an actual printed word or character, it could even be an empty line or a space in the page which is being sent before the Header.

 

To assist, we need to see the page code in order to find the source of the problem. Please post the php code here. Seeing the generated html won't help us in this case.

nol,I have no idea why that first script of your fails on your set-up. I un-zipped those files, created a db and user, used the SQL file found on Friks' Tutorial and *poof* I had it working first time I tried to register and then immediately logged in.Also, the second Tutorial you are trying to set-up is written for Intermediate to Advanced php users, with classes and Object-Oriented programming concepts. I don't think you are there quite yet. I would suggest you step back to using Frik's script. IMHO. But that is only my opinion...
