 * I just installed my site, [http://www.arkanian-enterprises.com/wordpress](http://www.arkanian-enterprises.com/wordpress)
   and it appears to work fine, except that when I try and login as the Admin I 
   receive these errors:

 * Any idea what could be causing this, or how to fix it?
 * Thanks.

 * Looks like some of the wp-includes files didn’t make it. Upload the entire folder
   again.

 * Tried reuploading the folder twice and no change. Is it possible the error is
   coming from elsewhere.

 * It’s possible you have a plugin conflict. Have you disabled them and tried ?

 * Sorry, how would I do that? :/ I’m very new to this.

 * Login to your admin and click on “Plugins”
    Deactivate them all and see if that
   helps. If it does activate them one by one until you find the offender.

 * there is whitespace or characters after the closing `>?` in your wp-config.php

 * I had the same error… it was the white space/extra returns at the end of the 
   wp-config.php
 * Something so simple and invisible unless you know to look for it… I spent a couple
   hours attempting to troubleshoot on my own before finding this and then it took
   all of about 10 secs to fix the file and re-upload and then all was copasetic…
   🙂
