My website is currently hosted on HTML, but I want to transfer it to WordPress. After installing a WordPress script, I faced the challenge of connecting my domain to WordPress. Unfortunately, I completely forgot how to do that and need some assistance. Could you explain the process to me, please?

Additionally, I think there may be something strange going on with my domain registrar as my previous website is still functional despite being completely removed from the hosting. It has been almost 48 hours since I initiated the DNS campaign, but there has been no change. This is quite concerning to me.

If a website is accessible on another computer from the same provider, then the problem might be with your cache. You don't need to do anything drastic; simply clear your browser cache as mentioned before.

If you're not sure how to clear your cache, you can easily find step-by-step instructions by searching "how to clear the cache in Chrome" or any other browser on Google. There are plenty of tutorials available with pictures and even videos on YouTube for those who prefer a more visual approach.

Alternatively, you could use software like CCleaner to clean up your cache and optimize your system performance.

For added security, it's recommended to check what's written in your hosts file located in windows/system32/drivers/etc.

When purchasing web hosting and a domain, the primary domain you select during the order process is automatically attached to your hosting package. It will already be added to the cPanel and you won't need to take any further actions. The server automatically creates the DNS zone for this domain, and all its records can be found in the Advanced DNS Zone Editor menu.

Adding new domains is also straightforward. First, create a new domain, then create an account with a hosting provider. Next, enter the NS (name server) details into either the domain admin panel or the hosting provider's panel. This could be an IP address or just the name of the NS server, depending on how it's set up. Finally, wait for it to finish directing.

In short, that's it - a simple process for adding new domains to your web hosting account.

You'll need to access your domain registrar's control panel and locate the DNS settings section. This is usually found under the "Domain Management" or "DNS Settings" tab. Once you're in the DNS settings section, you'll need to update the nameservers to point to your WordPress hosting provider. Your hosting provider should have provided you with the necessary nameserver information, usually in the format of ns1.hostname.com and ns2.hostname.com.

Update the nameservers in your domain registrar's control panel, and save the changes. This process is called a DNS propagation, and it can take anywhere from a few hours to 48 hours for the changes to take effect globally. However, it's strange that you're not seeing any changes after 48 hours, and your old website is still functional.
I'd say that this is a red flag, and there might be an issue with your domain registrar or the DNS propagation process. It's possible that the DNS changes haven't propagated correctly, or there's a caching issue somewhere along the line. I'd recommend checking the DNS settings again, and ensuring that the nameservers are updated correctly. You can also try using a DNS propagation checker tool to see if the changes have propagated globally.

Another possibility is that your old website is still cached somewhere, which is causing it to appear functional. This could be due to a caching issue at the domain registrar's end or even a CDN (Content Delivery Network) caching issue. In this case, you might need to contact your domain registrar or CDN provider to clear the cache and resolve the issue.
I'd also recommend checking your WordPress hosting provider's control panel to ensure that the domain is properly configured and set up. Sometimes, a simple misconfiguration can cause issues with DNS propagation.

In any case, I'd recommend reaching out to your domain registrar and WordPress hosting provider to get to the bottom of the issue. They should be able to provide you with more insights and assistance to resolve the problem.
As for the transfer process, once the DNS issues are resolved, you can proceed with transferring your website to WordPress. You'll need to create a new WordPress installation, and then import your old website's content into the new installation. This can be done using a variety of plugins and tools, such as the WordPress importer plugin or a third-party migration tool.
