500 Internal Server Error

Hi jenahfsmith,
In this case, the cause maybe by your host. You should increase some values in the php.ini file. Here's requirements for the Kuteshop theme
Before you begin the install, checking to ensure that you have the minimum requirements for Kuteshop is WordPress 4.4.0 or highter, PHP 5.4 or highter and MySQL 5.4 or highter. Recommended PHP Configuration Limits
Many issues that you may run into such as; white screen, demo content fails when importing, empty page content with Fusion Builder and other similar issues are all related to low PHP configuration limits. The solution is to increase the PHP limits. You can do this on your own, or contact your web host and ask them to increase those limits to a minimum as follows:
max_execution_time 180 or more
memory_limit 128M or more
post_max_size 32M or more
upload_max_filesize 32M or more
If it does not work, please provide your Cpanel or FTP accounts details via secret information area. I would like to check your host and fix it.
Regards
