Thank you for the prompt reply. I still cant change my password and unable to log in

Esmi I am checking with my hosting provider as I am unable to log into my cpanel as well.

Gosh this is so scary and the website been blocked

The hosting provider should be able to assist you and track down what happened. What is important is that the hosting provider helps you find out from where they went in so you close that door next time ??

Thank you all so much for the information. I will update you the latest progress…

* so sad that this is happening….*

But I dont understand why am I unable to log in to my WordPress ?

Maybe your password was reset by the malicious user? In that case refer to the document Resetting password (https://codex.www.ads-software.com/Resetting_Your_Password) to change your password via FTP, if you still have access via FTP.
