I can’t edit

Hello,

It happens to me exactly the same.

Have you found the problem?

I have version 6.0.1 of WordPress and the following plugins activated:
– 404 to 301 – Redirect, Log and Notify 404 Errors
– Akismet Anti-Spam
– Astra Pro
– Duplicate Page
– ManageWP
– Elementor and Elementor PRO
– GDPR Cookie Compliance
– Head, Footer and Post Injections
– iThemes Security
– Lenix Elementor Leads addon
– Save SVG
– Site Kit by Google
– Slider Revolution
– W3 Total Cache
– WP Show Posts
– Yoast SEO

I solved the problem by changing the plugin, now I use this one:
