If someone install CWP, need to first upgrade Roundcube.. Because, all releases (6 and 7) have bug in roundcube.

I solved that problem. Downloaded 1.3.4 version of roundcube and changed all files and installed again and fixed..

Has there been resolve to this, we're getting a 500 error on a brand new install of CWP7 Pro.  Please advise.

I think it's better to upgrade roundcube.
You can use the following HowTos:

Their versions are a bit outdated, but I already use them and works downloading the latest stable version.
Don't forget to backup before.
