Hello,

My recent upgrade to CB 1.2.2, sh404SEF 1.5.9.434, and Multisites 1.2.26 didn't go so well.

All my sites were getting blank pages on the front end.

First, I:
- uninstalled patches,
- FTP'd CB Expert Only files
- Checked the CB database and users in CB tools
- Uninstall sh404 SEF, re-installed
- Purged SEF urls
- upgraded Multisites
- Reinstalled patches

And everything on the front end was blank. I had to restore my files and db for the site to work again.

So, what is the latest supported version of these components, and is there a page where this is listed out for easy reference?

Would you please send us the CB 1.2.2 in attachement of an email. See our contact page for the email.
The latest version that we have tested is CB 1.2.1

When you have a blank page, this is the symptom of a PHP syntax error and you may have a file "error_log" that will give you more detail.
