For what it's worth, I am still experiencing this issue, even on 4.1.8. I roll back to 4.0.20 to fix it.
1) Ubuntu 10.04LTS amd64
2) 4.1.8std
3) PHP 5.3.2-1ubuntu4.10 FCGI+PHP-FPM / Wordpress 3.1.2
I need to confirm but it looks like it is working with the recommended build. Thanks, at last
Yes, it is OK!
I had to disable the following filter to get rid of 403 errors since the upgrade:
SecFilterSelective ARGS "(alert|expression|eval|url)[[:space:]]*\("
SecFilterSelective ARGS "(&\{.+\}|(&#[[0-9a-fA-F]]|\x5cx[0-9a-fA-F]){2})"
