I can login my account, but can not access cpanel, when I click mange hosting, it shows: An error occurred, please try your request again
you do realise that your post title refers to 'mange'. A type of scabies that a dog can get.
I don't think there are any vets on the forum.
Now if it's a website or hosting issue?......
I take it that you do have a hosting account and not just a domain name?
