I copied my site over to a staging site, wanting to test the HTML migration. MOre or less immediately it spit out the following error message:
{“readyState”:4,“responseText”:“
There has been a critical error on this website.
<a href=“https://wordpress.org/documentation/article/faq-troubleshooting/”>Learn more about troubleshooting WordPress.
”,“status”:500,“statusText”:“error”}
I will add a secure not with login-credentials to the staging site. Feel free to play with it.
