Hello, AdamM,
Thank you for reaching out to us for assistance. We’re sorry to hear that you’re experiencing difficulties with importing demo content and encountering a 500 Internal Server Error when attempting to create a new menu, among other things.
We recommend checking the following:
– Ensure that your hosting environment meets the minimum requirements for the theme https://www.8theme.com/documentation/xstore/theme-installation/xstore-theme-requirements/
– Increase the PHP memory limit and execution time if they are set too low.
– Check the error logs on your server for any specific error messages that could provide more insight into the issue.
500 Internal server error means that there is some Fatal error in PHP script or on the server side. You can turn on debug mode in WordPress to see the error https://codex.wordpress.org/Debugging_in_WordPress
If it will not show any errors then contact your hosting providers and ask them to give you a server error log to check what is wrong.
Let us know the results and provide temporary wp-admin access, in case any further assistance is needed from our side.
Best Regards,
8Theme’s Team
