Https working but http not

Hi,

On my VPS I have Centos 6.3 with cpanel.
I've buy recently a SSL certificate(RapidSSL), after I installed the certificate.
When I access my domain with HTTP I get:
/http://www.MyDomain.com/cgi-sys/defaultwebpage.cgi
If I try to access a custom page(with HTTP) I get page not found -404.

But IF I access the DOMAIN OR A PAGE with HTTPS everything is OK and working.

I've installed the plugin: /http://wordpress.org/extend/plugins/wordpress-https/

the plugin working great, switch to HTTPS only the login and desired pages that is great too BUT of course what is not redirected to HTTPS and is redirect normal to HTTP all pages are not found(404)

For 2 days I Google'd, read topics, solutions but no solution for me, so interesting HTTPS working but HTTP NOT!

Can someone help me please, I'm stuck.

10x in advance!

P.S

My default .htaccess is:

# BEGIN
<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

 

I found the problem but not the solution.

When i install the RapidSSL certificate was request a dedicated IP so I bought a dedicated IP from my vendor who allocate me the new IP.
After the certificate was installed successfully.
I use the panel from my vendor to can use their name servers so not the cpanel. The problem is in httpd.conf because on port 80 remain the old IP and for port 443(SSL) was alocated the new IP.
So if I access my domain on port 80 with old IP was ok and new IP on port 443.
I've try to modify in httpd.conf to be the NEW IP but no chance(I try to modify for the domain the new IP in capanel but didn't let me), so I delete the certificate switch back to old IP but the same problem when I access my DOMAIN: cgi-sys/defaultwebpage.cgi.
I've rebuild my httpd.conf...etc no solution...I'm stuck

 

Solved!

The problem was from my mistake because I set the IP on certificate installation before to assign the IP for the domain, so old shared IP remains in httpd.conf for port 80 and for SSL was assigned the new IP on port 443.
Hard solution was to edit httpd.conf and easy solution was restore a backup or delete the certificate and rebuilt httpd via WHM and after assign the new IP for the domain and after to install the certificate.

10x for information...
