@vmarko Dear Marko, please ignore my previous reply. Problem has been solved and it was not W3 Total Cache Plugin related. In our case, if anyone has the same issue, it was the following code in the theme:
function defer_parsing_of_js ( $url ) {
if ( FALSE === strpos( $url, ‘.js’ ) ) return $url;
if ( strpos( $url, ‘jquery.js’ ) ) return $url;
return “$url’ defer “;
}
add_filter( ‘clean_url’, ‘defer_parsing_of_js’, 11, 1 );
Dear Marko,
We are also running into an issue, i am not sure if it’s update related however. In our case the blog -> edit.php and post-new.php pages show a white screen. Other pages don’t have problems. Quite a lot of Uncaught ReferenceError: _ is not defined etc. Any thoughts?
Much appreciated
Kind regards,
Tjerk
