Website homepage and admin panel error message?

I can’t open my Wordpress website nor can i go to the admin panel.

On the site home page the message shows!

The site is experiencing technical difficulties.

And on its admin page (wwww.mydomain.com/wp-admin) it shows!

The site is experiencing technical difficulties. Please check your site admin email inbox for instructions.

I first tried to rename theme folder, then i renamed plugins folder and then the newly updated plugins each separably. Nothing worked out.

Then I tried it by changing all php versions first from Select php version and then from Multi php manager.

All in vain.

How can fix this. What am i missing?

Thanks in advance for anybody reading and/or answering.
