Check the recommended server configuration for proper theme functioning:
PHP version 5.6 and higher
memory_limit – 128M
max_execution_time – 120
max_input_time – 60
upload_max_filesize – 40M
max_input_vars – 3000
Make sure your server is set up properly and the theme and content will be loaded correctly. Enough server configuration will also ensure fast speed and increase performance.
