Hi Rakesh,

Thank you for reaching out. We’re sorry to read you’re facing some server failures.

First and foremost, please check the WordPress prerequisites here:
https://wordpress.org/about/requirements/

For better performance and improve security, we obviously recommend PHP 7.3+. Nevertheless, if this is not possible for you (server type, incompatibilities with plugins, etc.), we recommend at least version 5.6.X.

We use WP Engine to host all our demos (https://wpengine.com/). The performance of your website can also be improved, like our demos, by WP Rocket (https://wp-rocket.me/). Finally, we may also recommend Imagify (https://imagify.io/), to shrink your images with lowest quality loss.

You can always add more stuff to improve your page loading time but this is a pretty good start.

Please be aware that too many plugins will considerably slow down your page loading time. So, we advise to stick to the bare minimum!
Our theme offers a built-in setup wizard if you wish to import one of our demos but you can skip it and start your website without installing any plugin or importing any demo content as only two plugins (Grimlock and Kirki) are actually required to make our theme perfectly work. Not every use-case is the same and we believe that our customers should be left with the decision of what to and not to install. You can rest assured that our theme will work fine and perform better without few plugins installed.

Finally, this topic might also catch your attention as one of our user shared the server configuration that has helped him to solve a similar issue:

Import Content page loading forever

We hope this will help! 🙂

Kind regards,
