OK I found it.
How to remove warning messages if you have manually updated Royal Mail prices:
The message code is located in 3 files at:
includes/modules/shipping/rmsmsmallpacket.php
includes/modules/shipping/rmamsmallpacket.php
includes/modules/shipping/rm1stlettert.php
The code you need to remove/comment out is:
===========
if(defined('IS_ADMIN_FLAG') && IS_ADMIN_FLAG == true && (int)@constant('MODULE_SHIPPING_RMSM_EXPIRES') <= time()){
$messageStack->add_session('The rates for the Royal Mail Shipping Modules (Airmail & Surface Mail) increased on '.date('jS M Y', (int)@constant('MODULE_SHIPPING_RMSM_EXPIRES')).'. A SQL patch is available to update them.<br /><a href="http://www.zen-cart.com/forum/showthread.php?t=46450" target="_blank">The support thread is here, click on the "<b>Last >></b>" link on the right to get to the most recent post.</a>', 'warning');
}
=========
The wording in each message is slightly different, but they all contain "The rates for the Royal Mail Shipping Modules" if you are searching for the code in the page, and they all start at line 21 in my files.
I hope this helps
