 * Since I upgraded to WordPress 4.3, I have been receiving the following message
   at the top of my page. The message is:
 *  The called constructor method for WP_Widget is deprecated since version 4.3.0!
   Use
 * __construct()
 * instead. in /home3/fouwhee2/public_html/wp-includes/functions.php on line 3457
 * I don’t know what to do now. Someone please help me out?

 * Try deactivating all plugins. If that resolves the issue, reactivate each one
   individually until you find the cause.
 * If that does not resolve the issue, try switching to the default theme for your
   version of WordPress to rule-out a theme-specific issue (theme functions can 
   interfere like plugins).

 * Matthew,
 * I deactivated all of my plug-ins, and that seemed to help. As I tried reactivating
   them, the issue became back and I tried to localize the plug-in that might be
   causing this problem.
 * I tried changing themes by previewing them, but the problem showed up on all 
   of them. I really don’t know what to do.

 * Were you able to?
 * Also have you tried reinstalling WordPress 4.3.

 * Matthew,
 * No, I wasn’t. Any one of them that seemed to cause the problem, I left deactivated.
   I will try reinstalling WordPress 4.3.

 * Do you have a backup of your website before this problem happened? You can always
   just restore a backup and get your website back to normal.

 * Matthew,
 * Unfortunately, I did not have a backup, at least not one that is recent.

 * Ok, did reinstalling WordPress fix the issue?

 * Matthew,
 * I know this may sound stupid, but where do I click to go to the page where I 
   can reinstall WordPress 4.3?

 * Go into the updates section under dashboard in your admin. You will see a re-
   install button in the top part of the page.

 * Matthew,
 * The problem seems to have been resolved. Reinstalling WordPress 4.3 seems to 
   have fixed the problem.
 * Thank you very much for your help.
