I went to update a client’s site to WordPress 3.7.

As usual, I backed up and downloaded the site prior to the update.

After the update, I got

Fatal error: Call to undefined function wp_get_current_user()

Awwww cwap.. The front and back end were dead. Fortunately , I found a thread at

http://wordpress.org/support/topic/fatal-error-call-to-undefined-function-wp_get_current_user-4

The solution there was to go to

/public_html/wp/wp-includes  and modify the capabilites.php file to add

require_once(‘pluggable.php’);

Note – your path might be different. You are looking for the wp-includes folder.

Now, there is a note there that copying and pasting the code won’t work UNLESS you manually retype the quotes using the single quote.. and….. they were correct..

So, I made the changes and  the front and back end came back to life. .. and my pulse and respiration returned to normal.

Oh, and I didn’t need the backup I had just run but it was a really nice feeling to know I had it.

And, a final note to the WordPress guys.. Stop scaring the stuff out of me with tricks like that.
