... so at 08:35 where you try to log in.. .. i enter my url....http://kristjan.eu/wp-admin/ And get error like : (nothing is displayed except this error )

Warning: Cannot modify header information - headers already sent by (output started at /data05/virt37173/domeenid/www.kristjan.eu/htdocs/wp-content/themes/kristjan/functions.php:1) in /data05/virt37173/domeenid/www.kristjan.eu/htdocs/wp-includes/pluggable.php on line 876

OK found a "solution".. i replaced functions.php in my theme folder... with a a random functions.php file from another site... everything seems to work...

Googled the problem... it happens often...

Narrowing down the problem reasons... Update-ing post when found the root of evil :D

OK that was interesting.... Everything was ok... Seems like file was corrupted or so...

I took similar functions.php file and inserted block by block the site code... Everything worked... :D .. i had text editor open, filezilla open... etc.... maybe it some program made some changes with file....

CASE CLOSED, PROBLEM TERMINATED :P

Yes, extra white space or lines at the top of the functions.php file will cause header issues. Were you able to get your own code back into the functions.php file?

If it happens again, look for extra spaces or blank lines or anything else before an opening php tag or after a closing php tag.
