Pulling down code?

Silverstripe Version: 2.4.13 (I know)

Question:
I have never used Silverstripe before, but I have a client with an old SilverStripe site that hasn’t been touched in years and the client is no longer in touch with the original developer, and there is a problem with the metadata. How can I access the code to fix this problem?

This would depend on the metadata - keywords and such you should be able to enter via the CMS. Other stuff may depend on extra modules the user may have installed?

The rest you’d probably have to fix in the Page template(s) that you’d find in the /themes/[yourtheme]>/templates folder.
