Website keeps reverting to old version




I need some advice on this… My client used WordPress Theme and his site keeps reverting to older version and all of the works I’ve done already gone because of this, what might be the cause on this? anyone have encountered like this before?

  • Hosting Provider -> Hostgator (We contacted hostgator and they said it’s not from their server because they can’t find it in their changelog) they get the site backup on last June 29 but still the site used older version and all of the plugins used are gone…

  • He used sitelock for site protection (We contacted sitelock and they said they have nothing to do with it)…

The site does not use any caching plugins…
Does hosting server or sitelock the one responsible on this? I have no idea what is causing this issue… What can you advice?

Thanks for the help!
