Hello,

It is possible that something was uploaded wrong or something is corrupt with your WP install, so you can try to download a fresh copy of the theme and install it.

But it seems like the reason why you're having this issue are low server resource settings.

Could you please try to increase these MASTER values or ask your hosting service to do it for you.

max_execution_time = 300
memory_limit = 128M
upload_max_filesize = 128M
post_max_size = 256M
max_input_vars = 3000

After you do this, you can try to install all required plugins and run import the demo.

Please note that after installing / activating this theme, you need to Install/activate all required plugins like WP Bakery Page Builder, Elated Core/CPT and Slider Revolution (+Contact Form 7 and WooCommerce if you plan to use shop). 

Then you can import the demo with our OneClick (Elated Options >> Import) or with native WP importer tool (Tools >> Import >> WordPress) via XML, located in the file you downloaded from ThemeForest website / XML.

Then you can go to Appearance >> Customize >> Homepage setting >> and then choose desired homepage.

Before that, please check your server resource settings. Check/increase these MASTER values or ask your hosting service to do it for you.

max_execution_time = 300
memory_limit = 128M
upload_max_filesize = 128M
post_max_size = 256M
max_input_vars = 3000

You can use this plugin in order to check it >> https://wordpress.org/plugins/wp-serverinfo/

Also, note that when importing a demo onto your site RevSlider slideshow has to be imported separately. To import a RevSlider slideshow from one of our demos please go to your WordPress admin panel Slider Revolution -> Import. Search for some-home-slider-X.zip located in the file you downloaded from Theme Forest / xml export folder and import that demo’s slideshow.

Also you can follow these guidelines on how to import the demo here >>
