Hello,

I am trying to use the one click demo import for my physio theme, but when I click on "import demo data" I keep getting Error: internal server error (500).  

I tried disabling other plugins but still issue persists. Can you please tell me the exact step to import the demo data?

From php logs:

[20-Aug-2020 17:45:34 UTC] PHP Fatal error:  Uncaught Error: Class 'XMLReader' not found in /var/www/html/wp-content/plugins/one-click-demo-import/vendor/awesomemotive/wp-content-importer-v2/src/WXRImporter.php:127

Found the solution.

I was missing the package php-xml on my server. After running the following commands, I was able to use the one click demo import:

sudo yum install php-xml

sudo systemctl restart httpd

sudo systemctl restart php-fpm
