The backend editor button is not clickable.

I've tried to change all files/folders attributes to 777 for this plugin. I've checked and increased some php parameters (phpinfo for my site - https://avtovoronka.su/php.php) I disabled all other plugins and changed themes. Changed the plugin to older versions.

Button still is not clickable. How can I fixed it?

There is another installed plugin (Hustle, for popups) that has the same problem - its dashboard even is not loading.
