Theme requirement
Before working with UniDash, please make sure your host is running WordPress 4.7 or higher, PHP version at least 5.6 (WordPress recommends PHP 7), and MySQL 5 or higher. Follow this checklist to ensure your host can work well with the theme:
Recommended PHP Configuration Limits
Many issues that you may run into such as; 500 Internal Error, white screen, demo content fails when importing, empty page content and other similar issues are all related to low PHP configuration. (There is a PHP info plugin to help you check these PHP settings easily in WordPress Dashboard > Settings) 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 (recommend 300)
- memory_limit 256M
- post_max_size 32M
- upload_max_filesize 32M
Cactus System Status Report
You can go to Dashboard > Cactus-University > About to see your system status as below. In case, you need to update some WP settings, please follow this guide http://codex.wordpress.org/Editing_wp-config.php#Increasing_memory_allocated_to_PHP
NOTE: If you have done all but still encounter this issue and your web server is Nginx. It might be a problem of Nginx server configuration has the too low response time. You should increase the timeout to 300, then try to reinstall the sample data
