Configration Error 404

How can I fix the problem ERROR 404 after the " Go to configration" page? My URL is “asbuzz”

Can you expand on the actions you’ve taken?

i am also getting the same error and tried to solve it but failed please help me in this regard.
Thanks in advance…

Need some more information than that?

here’s the picture of the message the website is showing

Did you try wp-admin
then settings > permalinks > plain/default?

yes, i did but the error remains

Dear Tech Team,

My first issue is pages are not updating says “update cannot be done”

My second issue is pages are showing 404 error when I click on the menus of my web site.

Kindly solve this issue or at least guide how to correct this issue.
