Error instead of WP Login

[kate.negley]

Hi there,

I created a basic website running off Wordpress. I then customized the theme. The website is up and running, fully functional. But now when I try to login to the Wordpress dashboard to edit the pages, I see a blank white page with this error:

Warning: Cannot modify header information - headers already sent by (output started at /home/content/66/10888366/html/wp-content/themes/neuro/functions.php:358) in /home/content/66/10888366/html/wp-includes/pluggable.php on line 875

Any ideas??

Thanks in advance!

Hey Kate,

My guess would be that something probably got messed up when you were customizing the theme. Are you writing out any text before calling Header()? This thread may help:

Hi guys,

Thanks for the fast response! :)

I did use a free theme then customized it. I am more of a designer than programmer (probably obvious!) so I'm not sure where to look in my code for the error - even after reading that helpful article, dom246.

This is what I have in my header.php code:

check your code this error cuase extra white space between php tag remove all space from php tag and then check

[cwarn23]

To elaborate more line 20-29 is the error lines because the white spacing before those methods are what is causing the error. If you need whitespacing before the header function then place the html in a variable and display it after the all the header() functions have been called. Note that new lines can be stored as "\n" in double quoted strings if you plan to store them in variables too.

Thanks guys! I wish I understood this problem more but I'm just not grasping it. I made the changes per your suggestions (in the following code) that I thought I understood - but still get the same error. What do you recommend as next steps? I need this problem fixed. Thanks!!
