Confusing error message at top of Wordpress re Theme, can anyone advise?

I have the lush theme installed on Wordpress and I have this message that won’t go away inside wordpress, I not sure how to resolve it.

I’m total newbie/hack so bare that in mind, thanks!

Envato_Theme_Installer_Skin::feedback($string) should be compatible with WP_Upgrader_Skin::feedback($string, …$args) in /home/customer/www/ on line 372

Hi @dominicw78,

Please contact the author of your purchased theme, the theme author will assist you.

How to contact an author to get support or for any technical query:


The theme is not compatible with the latest version of WordPress. Download and install the previous version of WordPress or request a theme update from the author for the latest version
