Theme will not update to latest version

I’ve had our website up and running on the same theme for quite some time. I have been getting this message that I cannot resolve:

Theme Blvd Layout Builder : It looks like you don’t have the latest compatible version of your theme installed. For best results with this version of the layout builder, you should update to the latest version of your theme.

You’re currently using Commodore v3.0.11.

On the Dashboard, however, the following message is displayed:

Themes

Your themes are all up to date.

I have my Envato username and API key entered in the Configuration section of my site.

I’m not sure what to do next. I believe the latest version of this theme is 3.0.15.

Thanks in advance.

Hi

If you purchased the theme from envato market then to get auto update features you can use Envato Market WordPress Plugin. This plugin helps customers receive updates to their premium wordpress Themes & Plugins purchased through Envato Market (ThemeForest & CodeCanyon).
you can download the plugin from here:

Using this Envato Market WordPress Plugin you will see:

  1. Latest version (need to update version) number
  2. Details view option for the latest version

otherwise you can download the update version from Envato Market Downloads page and update manually using ftp.

If you contact the theme author they can guide you.
