Not if you are UPDATING/UPGRADING your forum vs. INSTALLING the software for the first time or as a fresh/new install.
Who mentioned a new install? This thread is about an update and the following is taken from the upgrade instructions text file:
"You will also need to copy over install/styles/common.css and install/styles/admin.css from the install directory to the corresponding forum styles location."So I'm just trying to confirm that this is something that the upgrade script won't do, so in other words I need to do this manually before running the upgrade script, right?
