 * I am getting this error on my website marrakeshhaircare.com – on both the live
   site and the wordpress back end. I went into my FTP and found a document in there
   labelled “error_log” opened it and it says the following:
 * [15-Aug-2016 11:27:30 America/Denver] PHP Fatal error: Call to undefined function
   wp() in /home/marrakf2/public_html/wp-blog-header.php on line 16
 * I opened this file and on line 15 and 16 it says:
    15 // Set up the WordPress
   query. 16 wp();
 * what should the correct function be there?
    Any help is appreciated.

 * Try [manually resetting your plugins](https://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)(
   no Dashboard access required). If that resolves the issue, reactivate each one
   individually until you find the cause.
 * If that does not resolve the issue, access your server via [SFTP or FTP](https://codex.wordpress.org/FTP_Clients),
   or a file manager in your hosting account’s control panel, navigate to `/wp-content/
   themes/` and rename the directory of your currently active theme. This will force
   the default theme to activate and hopefully rule-out a theme-specific issue (
   theme functions can interfere like plugins).

 * Ok, try [downloading WordPress](https://wordpress.org/download/) again, access
   your server via [SFTP or FTP](https://codex.wordpress.org/FTP_Clients), or a 
   file manager in your hosting account’s control panel, and delete then replace
   your copies of everything on the server **except** the `wp-config.php` file and
   the `/wp-content/` directory with fresh copies from the download. This will effectively
   replace all of your core files without damaging your content and settings.
 * Some uploaders tend to be unreliable when overwriting files, so don’t forget 
   to delete the original files before replacing them.
