Hi there,
I would love to help you in fixing the issue in your wordpress website. Since, you have not share the details so consider my bid as rough estimate. Once, we will discuss everything then I will edit my bid accordingly.
I'll try to have this done in 1 day , but when you change the DNS , it usually takes 24-48 hours for it to be properly propagated to the new server, so that's why I mentioned 2 days in the bid.
Lets start.
Regards
~ Syed
