If the website is working on Hosting Account A and does not work on Hosting account B, it is not likely the Flynax script; but instead, a configuration issue on Hosting Account B.

I would recommend reaching out to your hosting account's support for assistance.

I would also recommend consulting with Flynax to do the website migration process for you.

Also, most good hosting companies will charge like $25.00 to migrate your website; however, some do it for free.
