Hello. how come my wordpress page say "Page Not Found
The page you were looking for could not be found. It might have been removed, renamed, or did not exist in the first place." it was working ok. now it says this message. and is it part of the outage php upgrade that is happening now?
Without access to your website, assuming that the page with the message appeared is still your chosen template, then you have a .htaccess issue. Login to your wp-admin and go to Settings > Permlinks, choose something that has index.php and you’ll be able to view your pages again first.
To solve the URL issue, inspect your .htaccess file to see if you have redirected every request to index.php except for the asset files.
A typical .htaccess contains:
# BEGIN WordPress
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress
