APEX

Hi,

I'm trying to hide the success messages in a page but it's not working.

(Works for messages on page load and normal ones but not the ones from Process success)

I'm following this guide:

https://apex.oracle.com/pls/apex/f?p=100309:33:

apex.message.setThemeHooks({
  beforeShow: function(pMsgType, pElement$){
  setTimeout(function() {
  $('.t-Alert').fadeOut('slow');
  }, 3000);  
  }
});

I put this code on the page settings > Javascript > Execute when page loads.

Apex version is 19.1

Thanks in advance.

EDIT:

Also I'm not using the default theme. I modified the colors and rounded the fields and buttons.
