how to add a line to functions.php without causing white screen

  • I purchased and am using a plugin called WordPress Car Dealer for one of my sites. After installing it I had a problem with the media uploader when adding a new page or publishing a new blog entry. When I tried to upload a file, the uploader would get stuck at the “crunching” part of the upload. I contacted the plugin’s author and he said I need to add the following line to functions.php:

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

    I guess I don’t know the right way to add the line. I tried just adding it to the end or the beginning of the file, but when I did that I started having a different problem. At first I would just get a blank screen after publishing a new blog post or creating a new page, so I would have to go back to the Dashboard (wp-admin) by re-entering the URL. Today it resulted in me seeing a blank white screen instead of being able to log in to the Dashboard.

    How do I add that line to functions.php without getting a white screen instead of wp-admin?

    If it helps, the theme is Celestial Aura (but I modified the CSS file).

  • As it’s a commercial theme, it’s not supported here. You should be asking the original develoepr for help with all of this (that’s part of what you pay for).

    But, becuase this is probably very simple, I’ll give you a hint… The opening and closing PHP tags are only needed if you are putting that line outside of a block of PHP code.

    I thought Celestial Aura was a free theme? I certainly didn’t pay for it!

    The problem (for me) with functions.php is that it has multiple opening and closing php tags.

    <?php
$themename = "CA";

blah blah lots of stuff here

?>

<div class="wrap">

<style type="text/css"> @import "<?php print get_option('siteurl'). "/wp-content/themes/". get_option('template') ?>/js/colorpicker/colorpicker.css"; </style>

more stuff including a JQuery that runs on page load and lots of functions

<?php
}
?>

    So I added that line to the end of the file after that last <?php } ?> and that’s apparently what was causing the white screen problem.

    There’s so many opening and closing PHP tags in there, I don’t know where to put that line I need to add. ?? Perhaps I will just ask a friend of mine that knows much more about PHP than I do.
