Hello,
I use a child theme and I updated the theme yesterday. A text error appears : a problem to the line 140 /www/wp-content/themes/activello/inc/libraries/epsilon-framework
So I checked and it’s this line : $response = $class::$method( $args );
If I erase “$class::” my wordpress works again but my logo in the header deseasperes.
I changed many things on my child theme, I wouldn’t like start again with a new one.
Thank’s if you can help me
