Need step-by-step instruction. Thank!

1. Go to ACP -> System -> Applications -> Check for updates button.
2. Go to ACP Dashboard.
3. Click the Download button on the update notification.
4. Follow the onscreen instructions. 

It's not that different compared to 3.x. You could also upgrade the same way as you upgraded previously (see http://www.invisionpower.com/support/guides/_/install-and-getting-started/upgrading-r19).

system/Theme/Theme.php(558) : eval()'d code on line 1760
