i've since rolled back my install by substituting the old concrete directory for the new one. Since the new upgrade failed midway, will this affect my rollback?

thank in advance

I "solved" this issue by uninstalling all non-core blocks and packages. I plan on reinstalling them and checking for updates after the upgrade process is completed.

Hi Mario - I appear to be having the same problem. My Traffic and stats package also does not work (blank page). I copy/pasted the erros into a Word document if you want to see the actual error but it appears similar to yours. I'm wondering how to "un-install all non-core blocks and packages"? Can I do that through the Bluehost CPanel - File Manager? ANy info would be appreciated.
Thank you,
Eric

hi eric,

Non-core block and packages just referring to blocks that don't come with a fresh C5 install. Just go to your backend Concrete 5 place where you install plugins. Choose to uninstall them from there. You can also ftp into your site and find the blocks and packages directory where you installed 3rd party plugins and delete them. However, that might not do a clean uninstall so it's better to uninstall from the backend if possible. Backup up your folders first, so you can reupload and reinstall them after the upgrade.
