No problem Conor. This is a tough issue. As far as the file goes, the information that was talked about before:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

Put that and only that into the .htaccess file. On the modifications part. Basically just make sure to deactivate all plugins before making the change to the .htaccess. Then test the site. The reason for this is because one of your plugins may be updating the .htaccess in a way that is causing the issue.
Continue using the generic template you stated you are using during your testing to ensure it is not template related.
Hopefully that will naturally fix your issue, and the problem will go away. If it does you will have to still figure out what plugin caused it, but at least you will have a good starting point to work with.

Hello Conor,

Did you try turning off all modifications,replace the .htaccess, and then re-enable your permalinks before turning on your modifications for testing?

This may sound a bit elementary but have you tried clearing your browser cache? Also tried another web browser like FireFox or Chrome to see if you get a different result?

Have you tried disabling your plugins/widgets since the issue started? If not go to your wp-admin, click on Plugins -> Installed Plugins -> Then click Deactivate on each of your plugins. What you want to do after you have disabled all of them, is turn them on one by one and test your WordPress editing ability to see which one caused the problem. Odds are this should fix your issue. Hope this helps.

No problem, glad to help!

Your going to be looking for something similar to this:

AuthType Basic
AuthName “My Protected Area”
AuthUserFile /path/to/.htpasswd
Require valid-user

Ultimately, if you don’t intend on password protecting your site in that way, just delete that section from your .htaccess file. That should get you back up and running. Hope this helps!

Looks like your hosting provider 000webhost is not resolving the nameservers you have setup on your domain. In essence the nameservers you are using to connect to your hosting, are not either the right ones, or your host has stopped your hosting account. I would recommend contacting your hosting company as soon as possible to find out what is going on with your hosting situation as they should be able to provide you insight into what is happening on your hosting account.
