Reposted because I kinda hijacked someone else's thread:
Just tried a different 2.2.1 > 2.2.2 upgrade method:
1. Make copy of current HTML directory (2.2.1).
2. Replace cms, jsparty, auth_openid and sapphire directories with those from the 2.2.2 download.
3. Run /db/build?flush=1 on frontend - OK
4. Go to CMS and click "Files and Images" tab (/admin/assets)
5. Fatal error: Class '' not found in W:\html\sapphire\filesystem\Folder.php on line 104
I have checked this file and there is no line 104. It's like 70 lines long.
Problem does not occur when I do a fresh install using the very same archive.
Anyone experience something like this?
Could incompatible code be the culprit for such an error (I have two custom page types, one of which has various File and Image upload code)
