Redirect loop upon installing SSL certificate on Bluehost

David, Are you sure the SSL you purchased work with sub domains too? Because I have seen that to cover sub-domains used SSL companies are charging extra.

Hello. Yes, Bluehost has two options – one for the domain and one that covers the domain and all subdomains. I chose the option that covers all subdomains.

Thanks for the thought, though. ??

Okay can you please open your wp-config.php file which is under blog directory and add below lines in to it or if you already have define it but having different URLs then change as per below. Then save the file and check again.

define(‘WP_HOME’,’https://blog.huntergeophysics.com’);
define(‘WP_SITEURL’,’https://blog.huntergeophysics.com’);

Thank you; I added those two lines to the end of the file and tested the main blog page and its admin area. Sadly, nothing has changed.

It looks like it fixed first issue now we have to figure out that sub domain is linked correctly with blog directory on server.

Use below article as help and let me know if it resolve your issue.

Sorry, but that hasn’t fixed the first issue… it’s still displaying erroneously on all of my devices.

And the link you sent is to an article that explains how to create a subdomain. I don’t need to do that…

If you seen source code of page https://blog.huntergeophysics.com you will see stylesheet URL like below.

https://blog.huntergeophysics.com/wp-content/themes/HGtheme/style.css

But if you try to access above URL you will receive “Page Not Found” error.

Now if I tweek it something like below it will work.

https://blog.huntergeophysics.com/blog/wp-content/themes/HGtheme/style.css

And this means sub-domain is not pointed correctly with sub directory called “blog”.

Ah ok. Well I checked the Bluehost CP subdomain area and it shows that the blog subdomain is pointed at the correct directory…

Here’s a screenshot of my subdomain list: https://dl.dropboxusercontent.com/u/4446393/Screen%20Shot%202016-01-07%20at%202.01.26%20AM.png

Thank you again for your advice.

Should I remove the subdomain and recreate it in case some settings somewhere aren’t working? Or will this irreparably break the website?

Nope, It will not break the website. You can delete and recreate it and make sure if it asks for http or https you select https.

Ok. I have recreated the subdomain. It didn’t ask for http/https, only the directory. Still not working, sadly.

Sorry, but it’s almost 3am here, so I’m heading to bed. Thank you for all your help this evening, and hopefully I’ll talk with you further once I awake tomorrow.

Thank you again. ??

Ok, I’m back online now.
Do you have any other suggestions please?

Thanks again.

Look into this for enabling wildcard ssl on subdomain with Bluehost.
Needs to be done from the .htaccess. If you have any questions their support should be able to help you with it.

Thanks, Shortstraw8. The instructions in that link fixed my problems 1 and 2 completely.

However, I still need to enable HTTPS for the /astro/ subdomain.

Using the instructions you provided, my root folder .htaccess file now looks like this:

# Use PHP5.4 Single php.ini as default
AddHandler application/x-httpd-php54s .php
# Changed PHP handler from application/x-httpd-php54s to application/x-httpd-phpbetas on Thu Dec 17 15:20:02 MST 2015.

 # Custom subdomain .htaccess SSL + WordPress
        RewriteEngine On
        RewriteCond %{HTTP_HOST} ^blog.huntergeophysics.com$
        RewriteCond %{REQUEST_URI} !^/blog/
        RewriteRule ^(.*)$ /blog/$1
        RewriteCond %{HTTP_HOST} ^blog.huntergeophysics.com$
        RewriteRule ^(/)?$ blog/index.php [L]
        # End custom subdomain .htaccess

So I tried to add a new section to that file as follows in order to get /astro/ to use HTTPS as well:

# Custom subdomain .htaccess SSL + WordPress
        RewriteEngine On
        RewriteCond %{HTTP_HOST} ^astro.huntergeophysics.com$
        RewriteCond %{REQUEST_URI} !^/astro/
        RewriteRule ^(.*)$ /astro/$1
        RewriteCond %{HTTP_HOST} ^astro.huntergeophysics.com$
        RewriteRule ^(/)?$ astro/index.php [L]
        # End custom subdomain .htaccess

While the /astro/ installation still loads fine, it only loads in HTTP, not HTTPS.
Could you recommend a way of getting this separate subdomain to load in HTTPS please?

Thank you again for your help getting my main /blog/ installation up and running, which was my highest priority. ??

David.
