IMPORTING DEMO

> i just purchased a new highend theme and having trouble importing a demo as it times out when ‘select all’ is used. after importing each element separately i’m still not getting the demo.
> i added this to the config file but nothing changed… Add the following code to the very bottom, right before the line that says, “Happy Blogging”:
​

define( ‘WP_MEMORY_LIMIT’, ‘128M’ );
set_time_limit(120);
> can you please help ? i’ll submit site url, etc., upon response to this note.
