Hi @testing123,
Thank you for buying our theme. We hope it will meet all your expectations. 🙂
In most cases, these type of issues are caused by server misconfigurations. Please check the WordPress prerequisites here: https://wordpress.org/about/requirements/
For better performance (and better security) we obviously recommend the version 7.2 for PHP. Nevertheless, if this is not possible for you (server type, incompatibilities with plugins, etc.) we recommend at least version 5.6.X.
We really suggest you to reset your database and relaunch the setup wizard to install the theme, as it will programmatically do every steps for you.
You can easily reset your WordPress database using WP Reset (https://wordpress.org/plugins/wp-reset/), activate Elementor manually and start fresh with our setup wizard.
We’re waiting for your feedback.
Regards,
