Error after update

Hello, uwe1963,

It looks like that error is referring to a problem with the Envato Market WordPress Plugin. It does not show on the front end of your site to the site visitor. You should contact the author of that plugin.

I have alreday deletet this plugin.

It looks like there is still some code left over. You should contact the plugin author to learn how to clean it up.
