Admin Bar Missing on Front End

I recently switched a site I’m working on via localhost to the server.

One of the things that has gone wrong since moving is I no longer see the admin toolbar on the front end of my site. It works fine on the localhost so assume it’s something tied to the switch online.

Here’s what I’ve tried to fix it:

+ check wp_head() and wp_footer() function in header.php and footer.php respectively.
+ Switched to Twenty Fifteen theme
+ Verify the checkbox is checked in user profile option “Show Toolbar when viewing site”
+ Logged in, logged out
+ Disabled all plugins.
+ define(‘WP_DEBUG’, true);
Set to true with all plugins on I got two error messages.
First error message:
Notice: The called constructor method for WP_Widget is deprecated since version 4.3.0! Use
__construct()
instead. in /home/chickspi/public_html/WICTest/wp-includes/functions.php on line 3457

Second error message disappears when I disable all plugins:
Notice: has_cap was called with an argument that is deprecated since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in /home/chickspi/public_html/WICTest/wp-includes/functions.php on line 3570
