Finding # sign in path

I am working on a project that involves migrating a WordPress installation from point A to point B. It should be fairly simple, but neither manual nor plugin-based transfers are working. To explain:

Point A is a fairly standard installation of ‘demo.com’, and I am trying to migrate it to a subdomain (point B), say ‘c.example.com’. Of course I can migrate the code, plugins, themes, etc just fine, however when I bring over the database, everything goes haywire (and I have made updates to the site URL / home URL / some permalink structure within the database).

A snippet of code from within the tag shows some interesting information:

<link rel="stylesheet" id="parent-style-css" href="http://c.#wp-content/themes/Example_theme/style.css?ver=4.4.2" type="text/css" media="all">
<link rel="stylesheet" id="style-css-css" href="http://c.#wp-content/themes/Example_theme/style.css?ver=4.4.2" type="text/css" media="all">
<link rel="stylesheet" id="layout-css" href="http://c.#wp-content/themes/Example_theme/css/layout.css?ver=4.4.2" type="text/css" media="all">
<link rel="stylesheet" id="main-css" href="http://c.#wp-content/themes/Example_theme/css/main.css?ver=4.4.2" type="text/css" media="all">
<link rel="stylesheet" id="shortcodes-css" href="http://c.#wp-content/themes/Example_theme/css/shortcodes.css?ver=4.4.2" type="text/css" media="all">
<link rel="stylesheet" id="mediaelement-css" href="http://c.#wp-includes/js/mediaelement/mediaelementplayer.min.css?ver=2.18.1" type="text/css" media="all">
<link rel="stylesheet" id="prettyPhoto-css" href="http://c.#wp-content/themes/Example_theme/css/prettyPhoto.css?ver=4.4.2" type="text/css" media="all">
<link rel="stylesheet" id="responsive-css" href="http://c.#wp-content/themes/Example_theme/css/responsive.css?ver=4.4.2" type="text/css" media="all">
<link rel="stylesheet" id="instag-slider-css" href="http://c.#wp-content/plugins/instagram-slider-widget/assets/css/instag-slider.css?ver=1.2.1" type="text/css"

Taking a closer look, you can see that the href/path does not include the ‘example.com’ domain name, and instead is replaced with a “#”.

http://c.<strong>#</strong>wp-content/themes/Example_theme/css/responsive.css?ver=4.4.2

Further notes, I have updated the wp-config file to define the WP_HOME and WP_SITE URLs, and this has no effect. .htaccess is also corrected for the subdomain (which additionally has no effect), it reads:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /c/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . //index.php [L]
</IfModule>

# END WordPress

The cause of this seems to be somewhere within the database, however there may be a file somewhere that is controlling this.

Any assistance is welcome, and very appreciated.

Thank you again for your time with my issue.
