Remove hacker access and fix site access

Job ID: 32388915

Budget: $30 – $250 USD

A previous dev i hired did not complete any job and instead is now trying to blackmail me to give him money. He has blocked access to my site until i pay him money.

When i try log in it says the gmail address is not verified. When you try register it says the same thing.

He has linked all the users to fake email addresses so no one has access.

I need someone to go into my server and fix the changes he made and remove any back door he has created.
