Error after upgrading Wordpress to 5.8.1

Hi.

My site https://slopiewnie.000webhostapp.com/

The WP version was 5.7.3. I have set up automatic Wordpress update. Today my website is not running.

There is a message:

“The site has a fatal error. Additional instructions have been provided in the message sent to the site administrator’s e-mail address.”

Hi there, I’ve checked your site and can’t see why the issue is happening.

My advice would be to fresh install unfortunately as we don’t have the support power to investigate issues from third party scripts etc, I can confirm this issue is related to a third party script of Wordpress or plugin/theme and is not related to anything on our side of things.

I’ve refreshed your .htaccess, wp-config.php file, disabled plugins, tried installing and configuring a new theme, enabled debugging but still nothing.
