The mentioned error may be due to a third-party plugins conflicts. Can you please disable any caching plugins you have on your site like W3 Total cache etc.

If, that doesn’t help please check this optimization practice if it may help you.

Please follow the best practices when updating your theme and plugins. See https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62 for more details.
- Clear all caches including browser cache then deactivate your caching plugins and other optimization plugins.
- If you’re using a CDN, please clear the CDN’s cache and disable optimization services.
- Test for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
- Reset your htaccess file by renaming it to .htaccess-bak. Then in WP Admin Menu, go to Settings > Permalinks and just click the Save Changes button.

define( 'WP_MEMORY_LIMIT', '256M' );
