HI Lula,

If you are using Kalium older than 2.0 then the easiest way to update our themes is if you use Envato Market plugin. Just follow this little procedure http://drops.laborator.co/pLFH

After you update the theme, there is a chance that we also updated some of the plugins that we offer.

To update those plugins to the latest version that we support, just go to Appearance > Install Plugins.

If you can't update any premium plugin there, go to Plugins > Installed Plugins and delete that plugin, then install it by going to Appearance > Install Plugins page again.

When you finish this procedure please go to Laborator > Product Registration and activate your product.
Then you will be able to update your theme very easily from your Wordpress updates.

P.S: If you are still using Envato Toolkit or Envato Market plugins you can delete them because you don't need them anymore.

P.P.S: If you have any problem when you update the theme please read this article https://laborator.ticksy.com/article/9429/

Glad to hear that

Will set this ticket as solved from here.
