 * I have been trying with no success to solving this fatal error for my WordPress
   theme Slash WP (which no longer has a developer so I am trying to do this on 
   my own). Do you have any ideas on how to get past this?
 * Here is the full error:
 * Fatal error: Call to undefined function dt_unify_url() in /home/*****/public_html/
   wp-content/themes/dt-slash/header.php on line 29
 * Listed below are the steps I took to try to remedy the situation:
 * 1. I commented out the line and it brought about another error in a different
   file on line 53. I commented out that line and it gave me another error with 
   the style css.
 * 2. I replaced all my files with fresh, 4.7.2 files (except wp-content)
 * 3. I deactivated all my plugins and I cleared my browing caches and cookies from
   the past week.
 * Any help would be appreciated, thank you.

 * The issue is in your theme. There may be a file missing or corrupt — whatever
   file dt_unify_url() is defined in. Upload a clean copy of your theme via FTP.
