Getting 404 on after accessing admin, theme errors on console

I can access my admin but on trying to work on anything in it..(pages, plugins..), all clicks go to 404. I thought its a server thing but chatting with support, they showed me all the errors in console. I attach here all the warnings pointing to /theme/wordmart/ esp. font… and the icons have all disappeared. This just happened overnight, I don’t know why.

Hello,

Could you please check how it works with some default WordPress theme like twentysixteen to understand is it our theme issue or not?

Regards

I have been looking for solution and found this which I included in the .htaccess file and I got my icons back
<IfModule mod_headers.c>
<FilesMatch “\.(ttf|ttc|otf|eot|woff|woff2|font.css|css|js)$”>
Header set Access-Control-Allow-Origin “*”
</FilesMatch>
</IfModule>
but the console still shows a couple of errors, and I cant change the theme without going to a 404 page.

Now I think this starts from chnaging my domain to www.

Never mind I change everything back to domain w/o www remove the above code and seems like everything is back in order.

Great, we are glad that you sorted it out.
