Upgraded to latest version and lost visual/text editor tabs

I am having the same issue and I have tried disabling plugins and still can’t figure what’s going on. Another thing I had to remove the Royal Child because it was causing me to not be able to get into the admin page. kept going to 404 page.

Thanks it was the browser cache. The other problem I have with the update is when I use the royal child theme it adds things to the .php in the child theme from either a plugin or something and causes issues to get into wp-admin. I have to change the child theme name to be able to get back into the wp-admin. I didn’t know if this is something you knew about or not this is what it adds to the child theme .php file only after the update. Not sure if it’s a plugin injecting something but I didn’t add any other plugins before or after the update and it was working fine before. I know going away from child theme also fixed the google map error as well. Maybe this code can help you figure whats causing conflict with plugins and the theme. I restored several times and it added same code each time I did the update even on a localhost.

add_filter( ‘login_errors’,
create_function(
‘$a’, ‘”Invalid username or
password.”;’
) );

add_filter( ‘the_generator’, ‘__return_null’ );

function schoolpress_wp_login_filter( $url, $path, $orig_scheme ) {
$old = array( “/(wp-login\.php)/” );
$new = array( “new-login” );
return preg_replace( $old, $new, $url, 1 );
}
add_filter( ‘site_url’, ‘schoolpress_wp_login_filter’, 10, 3 );

function schoolpress_wp_login_redirect() {
if ( strpos( $_SERVER[“REQUEST_URI”], ‘new-login’ ) === false ) {
wp_redirect( site_url() );
exit();
}
}
add_action( ‘login_init’, ‘schoolpress_wp_login_redirect’ );
