 * Hello,
 * after updating to the latest wp version my website is not responding and I got
   a “critical error” in php code. The plugin “Query Monitor” shows that the error
   is in the wp_config.php and it says “Constant WP_MEMORY_LIMIT already defined”.
   In the code I see “wp-config.php:96
    define() wp-config.php:96” any ideas? The
   website is running on the Astra theme + elementor. It is organised like so: astra
   theme-> astra child theme actevated->elementor pro plugin for website building.
   When I swotch to “hestia theme” or “neve” theme the website works, but I don’t
   really want to adjust it from scratch again to one of these themes, it’s a lot
   of work. Any ideas how to fix this bug?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fphp-errors-during-an-ajax-requestwp_memory_limit%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_
