#Hello, I am getting a very long and strange error message with the new Clear Line theme. Yesterday it only happened when I tried to edit a post, today it disabled the site entirely and I had to go into phpmyadmin to change the theme.
The error is:
"
Warning: Cannot modify header information - headers already sent by (output started at /home/lando/public_html/testlog/testblog/wp-content/themes/clear-line/functions.php:1) in /home/lando/public_html/testlog/testblog/wp-includes/pluggable.php on line 934
"I have no active plugins or widgets, and I have confirmed that this error does not occur when I use the 2010 theme.
I really hope this can be fixed, I really like the Clear Line theme...

#I should also add, I am using version 1.0.8, and that I noticed in this version that top search bar doesn't work, the one you see when you go to your site when you're logged in as the wp admin, but it does work in the 2010 theme.
I think I am going to try to go back to an earlier version of clear line and see if the problem persists.

#Ok, by trial and error I have determined that the cause of the problem is editing the php files in a text editor.
Even if I don't make any changes...just download and open the php file in notepad or wordpad, save and re-upload...it breaks the theme.
If I edit in the WP text editor, it's ok. And it doesn't happen with the css files, only the php.
Except that thing about the search box not working. That happened even on the fresh re-install...

Hey, I have had the same error (Warning: Cannot modify header information - headers already sent by output started at.../wp-content/themes/clear-line/functions.php:1 in...wp-includes/pluggable.php...), not in production site where I edit without problems via FTP, but in a test site also with Clear Line.
When I tried to edit the functions.php via FTP I have had that kind of errors in cascade and no access to login.php page. I've tried many times. The changes on file was right, because was just a change of ID numbers of two categories excluded from home, without changing anything else in a code that's already working on the site in production. Also, site showed the right modification, only admin wasn't no more accessible.
In fact, then I tried with admin editor and it worked, no errors.
