First things first, Envato sets the rules for item support, we as theme authors have zero control or influence over that. We do not see any support tickets from you; Please do check if you are Grandfathered for Avada support as explained here -> http://bit.ly/1SwDKpe
If this has happened to you, as described, then it will be that your WordPress was updated but you have not updated Avada to the latest version, which right now is Avada 5.2.3, you need to update to resolve this
When you update please ensure that you follow these update instructions:
