Admin not working

Hi

I downloaded and update the theme. I also upgrade WP to 5.3 and also all plugins upgraded. Now, when I go to admin > Pages I get the following error. The same is when I go to Posts. I can not see all pages and post. Only one page and post is show with following error.

I did not get any email on the admin email.

Regards

Hi Please try to enable your Debug mode so you know more details what is producing the error, this is most likely some of your plugin is not working correctly and producing a FATAL php error. Please turn on your debug mode and check details of error, that would suggest you which plugin is making problem. Then you can deactivate/delete that plugin. 

Check more details on this post please >> https://www.webfulcreations.com/there-has-been-a-critical-error-on-your-website/

Thanks once you know more details about error after debug mode on let me know so suggest you further solutions.
