I have never worked with such complex things, but usually 500 error comes when there is something wrong with permission of files or folders.

The page is not loading for me, so I am not able to take a look (it must be my office network ?? )

Can you try this,

Change the permalink structure to something new, save it… and then change it back to the old permalink structure. Save it.

Try accessing pages.

Can you provide links to both sites?
How did you move content to new host?

Yes, like Senff said, there is no wordpress installation on that domain.

There is something wrong with the domain or its DNS.
When I check whois of the domain, I get “Domain available”

https://iwhois.com/httpqegnetwork.com

I currently see Genesis theme, with some modifications.
Do you use any caching plugin?
W3 Total cache was giving me trouble while clearing cache on one of my wp installs. I had to keep it disabled for a while to fix it.

If they are not giving you access, there is nothing much that we can do.
You can request them to give access to FTP to download a backup, or ask them to generate a backup for you.

Or,

Increase your upload file size limit by editing the php.ini file
Find the php.ini file of your host, open it in a text editor and add the following:

php_value upload_max_filesize 10M

replace 10M with your new limit.

Install wordpress on a subfolder, and while installing tell WordPress not to index your blog in search engines.. test, show your work to members, and when done, uninstall/remove this installation

Where did you add the analytics code?

I am confused, if you added code from wrong account, you can get the correct code, and go back and edit the same file and put the new code right?

Hmm, try changing permalink to another one, check your site, and then go back to the old permalink structure.

So, what’s the error?

Make sure that you uploaded everything to public_html folder.

Glad to know that it got fixed.
The default index.html file of your host was really misleading ??

Looks like you hit the storage limit on your host?
