Make sure the functions.php file contains no blank spaces.

What do you mean no blank spaces? like inbetween each like there cant be a space? everything has to be bundled up?

First, change this <?php add_custom_background() ?> to this <?php add_custom_background(); ?> (added semi-colon).

If that doesn’t work, change it to add_custom_background(); (removing the PHP tags) and move it to the VERY END of your functions file. Right below add_action('admin_menu', 'mytheme_add_admin'); Also remove the ?> on the last line of the file.

When i did both of those changes i got another error
```
Warning: Cannot modify header information - headers already sent by (output started at /home/loboxd/public_html/wp-content/themes/Magazine-Channel/functions.php:3) in /home/loboxd/public_html/wp-admin/theme-editor.php on line 99
```
seems like the line 3 on functions.php is still messing things up

Try switching to the Twenty Eleven theme by renaming your current theme’s folder in wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

Do i do this through cPanel? Can you provide a little more detail on how to do this?

Yes – you can do this via the File Manager in cPanel.

Hey loboxd,

As dfwgreg said above, the functions.php might have a blank line at the top or bottom and it causes the issue.

Check the functions.php and remove any blank lines at the top and bottom.

Hey loboxd,

Did you try checking the functions.php if there’s any blank space?

Re-upload a fresh copy of the Twenty Eleven theme via FTP or the File Manager.
