We are facing a common problem sometimes. But this is a simple issue. for this, we can’t work properly on our site.

Use this code For the Elementor Editing and Demo Import Problem in your PHP configuration file on the hosting Server.
max_execution_time = 1000

max_input_time = 1000

max_input_vars = 1000

memory_limit = 512M

post_max_size = 512M

upload_max_filesize = 512M

and use the code of your wp-config php file

define('WP_MEMORY_LIMIT', '512M');


I hope,  your all problem will solve by the code.
