Fatal Error on recent upgrade

[starboard]

I just upgraded a very old site (1.6 CMSMS release I believe) and have tried to avoid as many errors as possible, and have fixed some. Haven't used CMSMS in a long time so a bit lost!

One I can't seem to figure out is when I visit 'Pages' I get this error:

Fatal error: Call to undefined method Content::URL() in /mounted-storage/home66a/sub008/sc39744-WSDY/dev/mysite/admin/listcontent.php on line 619

This also means when I visit the site I just get this error:

Fatal error: Call to undefined method Content::Secure() in /mounted-storage/home66a/sub008/sc39744-WSDY/dev/mysite/index.php on line 143

Any ideas?

You should upgrade in stages (see the docs site wrt upgrading).

And do a system verification after each step. it sounds like you have a problem with files not uploading properly.

Thanks guys, I had it set up on a test server luckily so I'll give this a go.

Annoyingly when you get a red cross on the system information, and you click the help icon none of the pages exist anymore so it's making figuring out what the issues are almost impossible.
