 * I am getting the following error. I am not sure what plugin may have created 
   this.
    Any suggestions?

 * This happens more times than not when you have a bad plugin.
 * If you have access to the admin, disable all plugins and check for the error.
   If the error is gone, re enable each plugin one at a time until the error comes
   back. This will help you find the bad plugin.
 * If you do not have access to the admin, you can rename the plugins directly via
   FTP. I found this to be pretty interesting. [http://www.wpbeginner.com/plugins/how-to-deactivate-all-plugins-when-not-able-to-access-wp-admin/](http://www.wpbeginner.com/plugins/how-to-deactivate-all-plugins-when-not-able-to-access-wp-admin/)

 * ok I can only ftp in. I did try renaming a few of the newer plugins but that 
   did not work. I guess I need to do all of them.

 * ok I renamed every plugin, including even Aksimet and I get the same error. Tried
   a new browser too. Do you get the same error. I am using a standard theme too.
   I think it is 2015

 * RESOLVED: I took out the extra white spacing on the class-wp-rewrite.php before
   the beginning < and after the last }
