    Whenever I try to log into my WordPress and edit my site (www.caketoons.net), I just get this screen "Warning: Cannot modify header information - headers already sent by (output started at /home/content/61/9813061/html/wp-content/themes/Webly/functions.php:1) in /home/content/61/9813061/html/wp-includes/pluggable.php on line 881"

    Can somebody please help me? I am a noob at this sort of stuff. Thanks!

    Have you modified either of those 2 php files ? Like put in an 'echo' for example ?

    Can you show us what is on line 881 of wp-includes/pluggable.php

    This may help - http://wordpress.org/support/topic/cannot-modify-header-information-headers-already-sent-by-functionsphp?replies=2

    I have tried to delete the "extra spaces" in the php files, but there are none anywhere.

    Also, the program that is seggested to use that was in the thread you sent me uses a program this is not for Mac, so I have no use for it.

    And to add to all that, how am I going to find line 881 of my "pluggable.php" because I am not going to count all of them. O_O

    The problem is in the functions.php file of your theme. You will need to use FTP to access your site to deactivate that theme:

    Any editor will show the line numbers, ..or should show the line numbers.

    Once I deactivate my theme, then what? Can I just upload a fresh version of the theme?

    Turns out, when I deactivated the theme, then went to my website, everything was white. Nothing was there.

    @TheMinecraftCookies

    If you have removed the problematic theme as WPyogi suggested, then revisit your site at yoursite.com/wp-admin instead of the front page. Log back in, and the default WordPress theme should re-apply itself.
