Most of the time this is not a hacking issue or server side problem specifically if you are continuously updating WordPress core software, this problem may be caused by WordPress Cache plugins or Caching proxies.

Check W3 Total cache WordPress page caching plugin:

A brief information about w3 total cache plugin: Every time a visitor’s web browser requests a WordPress page, WordPress engine runs a database query while processing PHP files and generates the requested page for the visitor but when you use Cache plugins like W3 total cache plugin it can help you speed up loading your WordPress based web pages by caching them and storing a copy of latest generated output of web pages in HTML format in disk space.
