I keep getting this message when i go to my forum
 

Does anyone know why i get this message when i go to my forum:

Unable to add cookies, header already sent.
File: /home/mmorpglo/public_html/Forum/includes/functions.php
Line: 5299

Can someone please tell me how to fix this.

I got this error when i intsalled a chatroom called flashchat. It worked fine but the next day it came up with a problem about config.php and people told me to upload a fresh config.php and fill out the details so i did. Now when i go to my website i have this error

Unable to add cookies, header already sent.

i think u have edited ur config.php file and you added < extra any where or may be you edited any templet and its missing some thing.

So what should i do.

Look at the config.php file on that line and see what you did.

Should i upload my config.php file in this thread.

if u made some change in config.php than just upload it again and be sure to add ur database detals as well and if some thing wrong with any templet that u made and forgot than just delete style xml file from your ACP and upload it again....

Its better if u can check your forum with another skin and if the same error than problem should be in config.php

Upload the config.php.new file from a fresh download and upload it to your includes directory. Delete the old config.php and rename the newly uploaded one to config.php. Edit the new config.php to match your server.

Or alternatively, goto line 182 of your config.php and remove the rogue "<".

Now i get this message

Disable all your modifications.

I got all these errors when i installed a chatroom called flashchat. Im going to unistall that and see what happens.

EDIT: Should i just delet the folder chat in my dorum directory because i can't access my forum at all so i can't get to the uninstallation of it.
