Hello Sadeq,

Welcome to your support management and thank you for choosing our theme!
Could you please import the demo following those instructions, and please pay special attention to PHP resources.

Step 1 - PHP resources

Since WordPress themes get more robust and complex, it's necessary that you release some more power from server. You can do that by editing php.ini file that you can find on your server, or contact your hosting service to do this for you. 

Make sure you meet these requrements and please don't skip this step, since it's probably the most important:

max_execution_time = 300;
memory_limit = 128M;
upload_max_filesize = 128M;
post_max_size = 256M;

Step 2 - PHP version

You should also make sure PHP version on your server is updated. 
5.6 will do the job, but you may use 7 as well.

Step 3 - Disable Plugins

You should disable ALL plugins except:
-Contact Form 7 
-Elated Core (CPT)
-WooCommerce (if you plan to use shop) 

Step 4 - Import

We advise that you do this from Google Chrome, no matter the Operating System.
Go to Elated Options > Import. On your keyboard press F12 and select "Console" view.

If you wish to import all demo content (pages, posts, widgets, options) you should choose "All" for "Import type" field. 

And if you wish to import media library for our theme, check "Yes" for "Import Attachments"
Then hit "Import" and follow console view.

If you see any red error showing up, you should refresh the page and try again.

Repeat the process until demo import is completed, following a successful "Import Completed" message, without errors in the console.

Step 5 - Enable Plugins

You should go to Dashboard > Plugins and enable all plugins.

Step 6 (optional) - Remove extra menu items

If you imported demo content multiple times, it's possible that you duplicated menu items several times. You should install this helpful plugin https://wordpress.org/plugins/quick-remove-menu-item/ 
Then go to Appearance > Menus and remove duplicated menu items.
After you finished demo import you can choose your homepage in Settings>Reading>Homepage Dropdown(just be sure to set your homepage to static page as well.

Thank You,
Kind Regards,
