All fixed.
After a lot of “Google-ing”
mod rewrite was already enabled.
I had to add the following code to the .htaccess in public_html
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
Did that and all the links worked.
I can now also access the admin panel.
Thanks again for your help Craig
