Blank Page error when changing password from a local install

Thank you Malevolentbunny, It's really weird, since you mentioned the problem was in the first error, I went ahead and removed the include 'partials.php'; from my functions.php file. And now that fixed the issue. What's in line 9 of the partials.php is this CSS line: color: #<?php echo esc_attr( $text_color ); ?>; I created this file to have a separate file for this inline CSS related to the Customizer and not having a bunch of styles in my theme-customizer.php file. I read it was a good practice to do so.
But the weird thing is all was working fine until I decided to change my password from the User Admin and I logged out. This is the code there is in the partials.php <?php function namaste_style_header() { $text_color = get_header_textcolor();

?>
<style type ="text/css">
    .company-name-box-header-title h2,
    .company-name-box-header-title h1 {
        color: #<?php echo esc_attr( $text_color ); ?>; 
    }
    .company-name-box-header-title {
        border-color: #<?php echo esc_attr( $text_color ); ?>;
    }
    .company-name-box-header-title h2::after,
    .company-name-box-header-title h2::before {
        border-top: 1px solid #<?php echo esc_attr( $text_color ); ?> ;
    }
<?php
if (  get_header_image() != '' ) :
?>
    .jumbotron {
      position: relative;
      height: 640px;
      background-image: url(<?php header_image(); ?>);
      background-repeat: no-repeat;
      background-attachment: fixed;
      background-size: cover;
      line-height: 200%;
      color: #fff;
      padding-top: 0;
      margin-bottom: 0;
      background-position: center top; }
<?php endif; ?>
<?php if(display_header_text() != true): ?>
    .site-title, .site-description {
      display: none; } 

<?php endif; ?> </style> <?php } ?>

I am calling the function like this from the theme-customizer.php:

include 'partials.php'; namaste_style_header();

What do you think is causing the issue, should I just abort intending to separate this code from the theme-customizer.php altogether?

Thank you malevolentbunny. Do you mean running that line from a command terminal?

Either from the command line or just opening the file. I work in linux a lot so I'm used to expressing file paths like that

I see this error: [26-Jan-2016 11:21:20 UTC] PHP Warning: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/Namaste-Theme/wp-content/themes/Namaste/partials.php:9) in /Applications/MAMP/htdocs/Namaste-Theme/wp-includes/pluggable.php on line 1228

Does this have anything to do with my having changed my password? I see there partials.php which is a file I created yesterday to house some CSS inline styles I use for the customizer.

I apologize for being so intense, I think I found the related error: [Tue Jan 26 12:21:09 2016] [error] [client ::1] client denied by server configuration: /Applications/MAMP/htdocs/.DS_Store, referer: http://localhost/MAMP/?language=English [Tue Jan 26 12:28:32 2016] [error] [client ::1] client denied by server configuration: /Applications/MAMP/htdocs/.DS_Store [Tue Jan 26 13:10:26 2016] [notice] Digest: generating secret for digest authentication ...

The problem is, this is over my head, what do you think I should do? Many thanks

Is the line actually

color: #echo esc_attr( $text_color ); ?;

If so then the issue is that you forgot to close the php tag and just threw it a question mark.
