This is one of the most annoying things as a WordPress developer – when the WordPress Importer fails and just leaves us hanging with a blank page.

If you’ve seen this before, and can’t find a solution no matter how much you search on Google, trust me – I feel your pain. So I won’t ramble on – here’s the solution.
Step 1
Go to your cPanel, scroll down to find “Select PHP Version”
Step 2:
Check the “dom” and “xmlreader” options.
Step 3:
Save. That’s it!

Good luck!
