Hi there. I have a question that is bodering me for some time. When performing an upgrade we will get a lot (or not. depending of the amount of changed ones) templates to revert, every time i did the upgrade i have reverted all of them and did the heavy task of redo all mods. What i want to know is if we do have to revert them or can just save them as they are. Thanks in advance.
If the upgrade script calls for you to revert them, you should do it as they have made changes to the default templates. The security token issue is a good example. The easiest way to do it is as Lynne said, compare them and mark the changes you have made and then revert them and re-add the changes. I usually mark any hacks lines I have installed with:
<!-- Hack Name goes here -->
code added to template
<!-- / Hack Name goes here -->
That way it is easier to find the changes and re-add them.
