Demo Installation error
- Make sure you didn't log out during installation.
- Make sure LiteSpeed cache is disabled on the hosting.
- Make sure Chrome didn't suspend/freeze the tab.
- Check hosting configuration, it should have PHP 7.4 or greater. We also don't recommend using shared hosting plans.
Some recommended hosting providers:
- EasyWP: https://www.easywp.com
- Cloudways: https://www.cloudways.com/en/wordpress-hosting
Plan B
If the previous step didn't help, we recommend using a freelance service to install the WordPress theme:
- Upwork: https://www.upwork.com/services/wordpress
- Fiverr: https://www.fiverr.com/categories/programming-tech/wordpress-services
- Toptal: https://www.toptal.com/wordpress
Trusted developers will help you with this task.
Plan C
You can try to install the demo locally and then deploy it to a live website. For example, you can use Localwp tool to create a local WordPress website (it works on your device) and then move it via All in One WP Migration plugin to a live website on the internet.
Plan D [Pro]
Increase PHP Memory Limit to 256 or 512MB or greater.
[Step 1]: Find the wp-config.php file at the root of the site then Edit.
Note: Always make a backup copy of the files before editing them.
[Step 2]: Search for the line that says “That’s all, stop editing! Happy blogging” and paste the following code right above it (or change it if it is already here).
define( 'WP_MEMORY_LIMIT', '256M' );
This sets your default PHP memory limit to 256MB.

[Step 3]: Save the changes. Then try to install the demo again.
