Forcing HTTPS

[JamesCI]

Hi,

 

I'm after a bit of help with forcing HTTPS for the whole site.

 

I have tried putting :

 

WHMCS System URL: https://mydomain.co.uk/

WHMCS SSL System URL: https://mydomain.co.uk/

 

It removes the URL from WHMCS SSL System URL and leaves https://mydomain.co.uk/ in the System URL.

 

It then does not force HTTPS when going to my website, it also stops forcing HTTPS for admin.

 

If I have:

 

WHMCS System URL: http://mydomain.co.uk/

WHMCS SSL System URL: https://mydomain.co.uk/

 

the HTTPS works but the only page of mine that isn't in https is the homepage /index.php

 

I've tried using the .htaccess but get a redirect loop.

 

Could anyone help with forcing the homepage through the .htaccess please?

 

Thank you

James
