I've just moved to another hosting yesterday..Everything was working brilliantly unless some ppl started to say that they ant login..Had a thought about it cos it was fine for me, then to test it out i deleted my cookies and ever since i cant login aswell...Entering details and when i hit login button it just redirects me to news page without actualy logged in..I can see my name on who is online section but thats it..Not sure if this is a cookie problem or smth with sessions etc..I rather solve this problem then moving back to other hosting compant so any help would be appriciated.

link: ekseriyet.com/dkp/
Fopen: on
Safe mode: off
PHP Version 5.2.17
MySql: 5.0.92
Eqdkp: 6.4.4

Also put debug 3 then got this error on login page

Unkown error type: [2] Cannot modify header information - headers already sent by (output started at /home/****/public_html/dkp/libraries/fileHandler/fileHandler.class.php:439)
File: /home/***/public_html/dkp/includes/session.php
line: 260

Edit: Wanted to try debugging on the old hosting but pages were all fine and there was no error..Strange because folders and files exacly the same on both hosting servers..Could it be a database problem maybe ?

did you also copy the database exactly? there is an entry in the config-table for the server-domain, that should match the one, where the system is installed

Yea database is same..Also domain is the same im not using a different domain i just changed the hosting servers so files are located elsewhere then previous one.

Although ive checked the db_config but didnt see any entry as server_domain..there is server_path, server_name, cookie_domain..not server_domain

You got some dead space in your header, that is why u cannot login. You cannot create a session when there is information already send. Check the source of your page. If you modified any files, clear the white spaces in the header.

I didnt modified any .php files really..
How can i check header and clear dead space..And how can this dead space come out all of a sudded by itself?
Any tips for a newbie?

How did you transfer the files?

Downloaded from old host by cute ftp then zipped them all and uploaded to the new server then extract.

If you got ssh access to the new system use lftp and mirror to sync the files to the new system

On it..Hope it will work

Thanks for the support btw..
