The style has no template edits, if a template shows outdated then it is because of a mod or a template edit that you have done.
Easiest way to compare templates is with
Notepad++ with the
Compare Plugin.
Open the outdated version in a new window then the default in another. Go to "plugins -> Compare". After that it is pretty easy to understand. After making the correct changes to the template, revert the outdated one for the style then paste the new version in.
