@jkreski Ctrl + F5 doesn't need those tags to work. It just works on its own. Goto the URL opera://settings/keyboardShortcuts and take a look at the "reload without the cache" command.
Not sure why it's not working for you.
They suggested a line of code to be put into my .httpaccess file.
It's usually .htaccess as mentioned at https://www.hostinger.com/tutorials/locate-and-create-htaccess, but understood about the password issue.
It might be something like this:
<IfModule mod_headers.c>
Header set Cache-Control "no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires 0
</IfModule>
that you need to add to your .htaccess file (just while developing if you want). But, if you don't get things exactly right, pages on your site won't load.
But, you really shouldn't have to do any of this and ctrl + F5 should be enough.
However, see https://support.hostinger.com/en/articles/1583501-how-to-clear-cache.
