I have just started receiving the following error messages on my site and when I try to log in to Wordpress..
Warning: Creating default object from empty value in /home/drshrink/public_html/wp-content/themes/platformpro/core/library/class.layout.php on line 164
(plus the same message on multiple lines) and..
Warning: Cannot modify header information - headers already sent by (output started at /home/drshrink/public_html/wp-content/themes/platformpro/core/library/class.layout.php:164) in/home/drshrink/public_html/wp-login.php on line 414
I'm not sure why this just happened. I am not a programmer, so please explain what I should do in detail.
Thank you for your help.
