New message note at whole website
How can I set that the new message note show at my whole website?
I'm sorry, but there is no option to customize it. You can write a CSS rule for this purpose, using the #wpf-msg-box id. However, this will change the style of whole notification, e.g. the topic is successfully deleted, subscription message, etc.
For example, you can change the width of the message box using this CSS code.
The code you should add in Dashboard > Forums > Settings > Styles > "Custom CSS code textarea."
Is there a shortcode for menu for messages? Like %woforo-profile-home%?
Yes, you can use the following /%wpforo-profile-messages%/ Shortcode URL.
