Strange redirection issues on wordpress from ssl with padlock to ssl without padlock

First time posting here so hopefully Ive got the right question in the right place.

I recently moved servers and then decided to add a ssl certificate. Since the move traffic has plummeted.

Looking at the site it seems that when you hit a site it doing some sort of redirect.

On the iPhone this is most obvious as hitting an article on http://essentialmac.co.uk you’ll see the padlock for a moment and then it looks like its redirecting and you’re served a https page but with no padlock up in the url area.

This is my .htaccess

# BEGIN W3TC Browser Cache
<IfModule mod_deflate.c>
<IfModule mod_headers.c>
Header append Vary User-Agent env=!dont-vary
</IfModule>
AddOutputFilterByType DEFLATE text/css text/x-component application/x-javascript application/javascript text/javascript text/x-js text/html text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon application/json
<IfModule mod_mime.c>
# DEFLATE by extension
AddOutputFilter DEFLATE js css htm html xml
</IfModule>
</IfModule>
# END W3TC Browser Cache
# 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

Can any please, please help. Thanks.

Given that this is a dated question and I see that the SSL (https://) is now running on the website mentioned by the OP, I feel this question still needs some closure to anyone else that has a similar issue:

1. Go and download Interconnect IT’s Database Search & Replace Script here
2. Unzip the file and drop the folder where your WordPress is installed (the root) and rename the folder to replace (screenshot)
3. Navigate to the new folder you created in your browser (ex: http://essentialmac.co.uk/replace) and you will see the search/replace tool
4. It should be pretty self-explanatory up to this point: enter your non-SSL links in the search for… field and the new URL in the replace with… field

You can click the dry run button under actions to see what it will be replacing before you execute the script. Once you’re done be sure to remove the /replace/ folder.
