Sometimes, the installation will fail after you try to import.
The first step, is to simply try importing again! If the error persists, try disabling all plugins, except the Kadence Starter Templates plugin and try again. You may have to try the import a few times for it to work. Otherwise, continue on for further instruction.
Contact Your Host
Some hosts have a standard upload limit for their users and often this is a very low limit that is unable to execute larger files like the content import. Please contact your host and ask them to set the following PHP configurations, at a minimum: (just copy and paste the below in a message to your host!)
memory_limit = 512M max_execution_time = 900 max_input_time = 900 post_max_size = 256M upload_max_filesize = 720M
While you’re in contact with them, ask them to ensure your site is running the latest version of PHP. After this is done, try importing again.
