Moved website location: Loading failed for the <script> - wordpress

Question

Building a Wordpress site locally, I've moved the website's location from localhost/company to the root (so localhost). I've gone into the settings in phpMyAdmin and changed the siteurl and home to 'http://localhost'.
Initially the site loads almost correctly (missing some images, elements etc). I presume these missing things are down to me not going changing the links using MySQL or the Velvet Blues Plugin.
However, when I refresh the entire website structure fails. Only a few elements actually load. If I inspect, I see the same error over and over.
Loading failed for the with source "http://localhost/company/wp-content/themes/grandtour/js/jquery-3.3.1.min.js".
This error continues referencing just about any JS file within /wp-content/ or /wp-includes/.
I'm unsure why it's still looking into /company/ despite me changing the phpMyAdmin settings.
Edit: A large amount of the JS files are being linked to like below:
<script type="text/javascript"
src="<?php bloginfo("template_url"); ?>/js/jquery-3.3.1.min.js"></script>
So it would appear that 'template_url' is still seen as localhost/company. Should this have changed when I changed 'siteurl' and 'home'?
Edit 2: The problem is now also occurring when I upload the site to a live domain, so it's not a localhost issue.

Answer 1

There are 2 thing you need to do when changing your website domain name or URL.
The first thing you would want to double check is that your SQL entries reflect the correct new URL. The SQL statement below will adjust the URL's inside wp_options, wp_posts and wp_postmeta.
UPDATE wp_options SET option_value = replace(option_value, 'http://oldsite-url.com', 'http://newsite-url.com') WHERE option_name = 'home' OR option_name = 'siteurl';
UPDATE wp_posts SET guid = REPLACE (guid, 'http://oldsite-url.com', 'http://newsite-url.com');
UPDATE wp_posts SET post_content = REPLACE (post_content, 'http://oldsite-url.com', 'http://newsite-url.com');
UPDATE wp_postmeta SET meta_value = REPLACE (meta_value, 'http://oldsite-url.com','http://newsite-url.com');
The next thing you want to adjust is your .htaccess file. The quickest way to do this is to go to Settings -> Permalinks and click save.
This will regenerate your .htaccess file, assuming that your new server has got the mod_rewrite rules enabled (most do). As mentioned in your comments, deleting the .htaccess is also a potential fix (but keep a backup just in case).

Answer 2

it is always better to keep your site with-in the directory instead moving to localhost which is primary location of your websites.
Primary location means where you can setup multiple websites in a directory.
If you are curious about URL structure you should look for Virtual Host.
Here is the setup guide on cloudways.com
So, Keep your site in htdocs folder if you are using XAMPP. and setup VHOST for pretty URL's.
after setup the V-HOST URL would be like http://yoursite.html
Everything will work perfectly without any error.

In the end, to solve the issue, I used this search and replace tool for WP databases. https://interconnectit.com/products/search-and-replace-for-wordpress-databases/
I'd updated the links using MySQL and also attempted using the Velvet Blues plugin, which is what I usually use without issue. However, this tool was able to find an additional 8 entries, which when updates, solved the issue.
