Thank you for reaching out to us. I checked your setup and I’m seeing the following error which could be breaking all of your pages:
Deprecated: Directive 'allow_url_include' is deprecated in Unknown on line 0
Try resetting your
.htaccess file by renaming it to
.htaccess-bak. Then in WP Admin, go to Settings > Permalinks and click the Save Changes button.
Make sure you’re using the updated version of PHP, you can find the recommended version numbers here https://theme.co/docs/version-compatibility
This also happens due to low PHP Memory Limit, contact your host to increase your allocated memory or do it yourself by adding this code in your
wp-config.php (see https://theme.co/docs/how-to-increase-php-memory-limit)
define( 'WP_MEMORY_LIMIT', '256M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );
Let us know how this goes!
