# Call to undefined function after functions.php edit.

 * Hi,
 * So I was adding the following code to my functions.php file so that I could display
   a list of daily tasks in the Dashboard area, this has worked perfectly on 3 other
   installs and initially appeared to be working fine also.
 *     ```
       add_shortcode('clarity','clarity_shortcode');
   
       function my_admin_notice() {
           ?>
           <div class="updated">
               <p><?php _e( 'Daily Tasks: <strong>Item1</strong>.', 'my-text-domain' ); ?></p>
           </div>
           <?php
       }
       add_action( 'admin_notices', 'my_admin_notice' );
       ```
   
 * Shortly after adding the code and clicking update I went back to Appearance >
   Editor to make further changes to the text that was being displayed, I clicked‘
   Update’ and when the site refreshed I received a ‘500 Internal Server Error’.
 * So naturally I went to the htaccess file to check for issues, but there are non
   here.
 * So I attempted to replace the functions.php file with a new, unedited one from
   the themes installation folder and now I’m recieveing this error:
 * > “Fatal error: Call to undefined function get_template_directory() in /…/folder/
   > members/wp-includes/functions.php on line 15”
 * I’ve moved:
 * require( ABSPATH . WPINC . ‘/plugin.php’ );
 * …above…
 * require( ABSPATH . WPINC . ‘/functions.php’ );
 * … in wp-settings.php but this hasn’t fixed the issue as suggested by some forum
   posts.
 * Can anyone help me fix this issue?
 * Thanks,
 * Best Regards,
    AFX

 * Hi
 * get_template_directory() functions does not exist in functions.php
 * Instead, get_temp_dir() is there, at line 1701.
 * Maybe the file you tried to default to was old and not updated. Try changing 
   get_template_directory() in functions.php from wp-includes to get_temp_dir() 
   and see if it works

 * Ok, try pasting this in functions.php
 * add_filter( ‘ot_show_pages’, ‘__return_false’ );
    add_filter( ‘ot_show_new_layout’,‘
   __return_false’ ); add_filter( ‘ot_theme_mode’, ‘__return_true’ ); load_template(
   get_template_directory() . ‘/option-tree/ot-loader.php’ );
 * replacing what was once there before. It’s around line 15.

 * Unfortunately still no luck:
 * > Fatal error: Call to undefined function load_template() in /home/argentumfxco/
   > members/wp-includes/functions.php on line 19

 * Oh, man, you really did a number on him! Is there any way you can restore from
   a backup? Right now I think this can be the only solution…

 * **I’ve worked out the solution for anyone else who runs into this issue after
   editing/adding code to functions.php.**
 * Obviously when a ‘500 Internal Server Error’ appears you should always:
    – Check
   your .htaccess file – Re-upload core files via FTP (**do NOT upload wp-config.
   php or wp-content folder**) – Search your functions.php file using a text editor(
   such as TextWrangler on Mac) for any code you have added
 * If you haven’t fixed the issue by this point you’re in the same boat as I was:
 * **Instead of looking at the functions.php file in the wp-includes folder**, navigate
   to:
 * **…/wp-content/themes/your_active_theme/functions.php**
 * and check for any flaws in this file.
 * If you are using a child theme make sure you check the child theme folder first
   and check to see if your site is running before looking in the parent theme folder.
 * I hope this helps!
