 * I can’t access my admin or website am getting the following error message:
 * Fatal error: Call to undefined function get_template_directory() in /home/content/
   51/10755751/html/web/indiacool/wp-includes/functions.php on line 17
 * The problem occurred when I tried to change some code in my theme’s ‘function.
   php’
 * Via FTP I’ve replaced the ‘function.php’ file with the original, unedited version.
   But I am still getting this error code.
 * Any ideas on how to fix this problem, so I can access my admin panel again will
   be greatly appreciated.
 * Thanks

 * Please clear both local browser cache **after** making sure to _manually clear
   any server cache in use_. You will need to discover which caching plugin and/
   or host provided server caching is in use to do so.

 * you seem to have replaced the wrong funtions.php; the error messages refers to
   the **/wp-includes/** folder, not your theme’s folder **/wp-content/themes/yourthemename/**.
 * use FTP to put an original copy of the **/wp-includes/functions.php** into the**/
   wp-includes/** folder
