I’m seeing this bug as well.
@ketanumretiya030 @shadnanm Keeping this post alive. I’m seeing this error, among others, using Divi in a Pantheon environment.
@shadnanm I want to agree with you. I’m not sure this is a Pantheon issue, but I am struggling to pinpoint to real problem outside of Pantheon or Divi.
Currently getting the error in conjunction with the following:
Uncaught Error: Call to undefined function _deprecated_file() in …/code/wp-includes/rss-functions.php:9 Stack trace: #0 {main} thrown
Uncaught Error: Call to undefined function get_header() in …/code/wp-content/themes/Divi/index.php:1 Stack trace: #0 {main} thrown
The get_header() error was an easy fix by adding
if (!defined('ABSPATH')) exit; to index.php in my child-theme.
Has anyone gained anymore insight on this? My site has been a lot buggier in the last month as well, so I feels like something is amiss and possibly getting worse.
