I did move the domain to another host/server, but prior to that I was able to log in.
Not sure what affect that has…

Yes.

The Twenty Twelve theme and all plugins are disabled.
Any thing else needed?

Thanks.

I tried the “How do I solve the Headers already sent warning problem?” but no luck.
Still get error on http://drdubrow.medave.net/wp-admin/
Here is the functions.php file within the theme:

<?php
define('FILES',get_bloginfo('template_url'));
?>

 <?php register_nav_menus(); ?>
<?php
    register_sidebar();
?>

<?php if ( function_exists('register_sidebar') ) {
register_sidebar(array(
'name' => 'Footer Sidebar',
'id' => 'footer-sidebar',
'description' => 'Appears as the sidebar on the custom homepage',
'before_widget' => '<div style="height: auto"></div><li id="%1$s" class="widget %2$s">',
'after_widget' => '',

'after_title' => '</h2>',
));
}

?>
<?php add_theme_support( 'post-thumbnails' );
?>

I have tried all 3 options above:
– deactivating all plugins
– switched themes
– reset the plugins folder

None of these fixed the issue.

Any other suggestions?
