Hi drnwag
The cause by your hosting. Please contact to your host provider, they will help you fix this issues. Here are the requirements for the TechOne theme
Before you begin the install, checking to ensure that you have the minimum requirements for the TechOne theme 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
memory_limit 128M
post_max_size 32M
upload_max_filesize 32M
Please do it and let me know your results.
