I'm working on a website of friends, they hosted their site years ago with a company that's no longer around. It hasn't been updated for years. We can't log on to the CMS anynmore (it was still possible last year) and I found it it runs on perch.
I figured out that the php version is the problem, but how can I now update the website? We do not have an account for Perch. Is it possible to update it through FTP and if so, where would I be able to download the newest version from? I have been looking in the site's folder but I can't figure out where the core files are.
