Hi,
If you use a plugin like Wordfence, please set it in learning mode.
Please make sure you have the latest version of the theme, 12.3
Please check if this code is missing from your .htaccess: https://www.screencast.com/t/iN0R93dD3p from our requirements https://forum.tagdiv.com/requirements-for-newspaper/ this requirement is not displayed in System Status.
Usually, after you set the code in .htaccess the WP editor works well.
Also, please check this guide about deny code https://forum.tagdiv.com/general-options-may-interfere-newspaper-theme/ ->
Please do a test using only tagDiv plugins and try to open the WP Editor.
Please check the console https://imgur.com/bRYwbvE if you have any errors when you try to open the wp editor, maybe is possible to be from the firewall or security module which blocks the admin-ajax.php request, which usually displays a 403 or 404 error.
If you don’t use a security plugin, please ask your host about this, maybe you have a security module that blocks this.
Also, if you are using Cloudflare, please make sure that is set as in our guide https://forum.tagdiv.com/cloudflare-cdn/, you need to disable the Rocket Loader.
Thank you
