My wordpress site was hacked and it’s no longer possible to login to the backend the regular way via the wordpress URL. A spamtext is presented on the site in live. The backup contains the hack as well, in order to fix this you will need to do a manual upgrade of the wordpress script, please see the below:
Besides the above, I want to make sure that the plugins and design templates remain active as before the spam attack, unless there is hacked material/spam in one of them. Please also make sure that the site gets back live so that it will be possible to login via the regular wordpress url site login page onwards.
