Wordpress site reverted from https... links broken - wordpress

Question

A site new to me as of today is broken. It is a wordpress site that the client tried to convert to HTTPS by themselves and it broke. They then tried to undo the work and go back to non-s version.
this has worked with one exception. The site is trying to redirect scripts to the SSL version.
For example trying to access this:
http://example.com/wp-includes/js/jquery/jquery.js?ver=1.12.4
is redirecting to this:
https://www.example.com/js/jquery/jquery.js?ver=1.12.4
(not the real domain.. obv)
Can anybody advise on how to fully revert?
If it helps, the Security Cert was purchase through Namecheap. The hosting is GoDaddy, and they attempted to follow the instructions here: https://designmodo.com/wordpress-https/
** edit **
SSL has been reinstalled, and it doesn't appear to be the problem. Something is redirecting scripts, removing the "wp-includes" from the url
the htaccess
# BEGIN GD-SSL
<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_USER_AGENT} ^(.+)$
RewriteCond %{SERVER_NAME} ^example\.com$ [OR]
RewriteCond %{SERVER_NAME} ^www\.example\.com$
RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]
Header add Strict-Transport-Security "max-age=300"
</IfModule>
# END GD-SSL
# 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

Wordpress save a lot of content and settings in the database, try installing this plugin Velvet Blues Update URLs to find-replace in your database the old values https://example.com with http://example.com some plugins save their own cache, so you probably need to go into a file browser and delete their cache folders.
If that doesn't work double check that your .htaccess is not redirecting your http traffic to https.
