HTTP ERROR: 500, zimbra license error, backup errors - urgent help needed

[oliver2uk]

Hi guys!

I have just downgraded Network Edition of zimbra to OSS and experienced few problems, which were already discussed few times here, but the solution doesn't work with 5.0.1 GA I am using.

My problem is very simple, after the downgrade from NE to OSS, I am unable to view/download attachments. I will always get this error:

HTTP ERROR: 500

system failure: Extension HTTP handler not found at /convertd

Caused by:

com.zimbra.common.service.ServiceException: system failure: Extension HTTP handler not found at /convertd
Code:service.FAILURE
at com.zimbra.common.service.ServiceException.FAILURE (ServiceException.java:183)
at com.zimbra.cs.extension.ExtensionDispatcherServlet .getHandler(ExtensionDispatcherServlet.java:141)

at javax.servlet.http.HttpServlet.service(HttpServlet .java:820)
at org.mortbay.jetty.servlet.ServletHolder.handle(Ser vletHolder.java:487)

Also, I am getting zimbra license error in admin, plus backup errors, etc ... All the NE functionality is gone, which is fine, however, all the NE extras stayed in admin and were not removed during downgrade from NE to OSS.

Please, can anybody help me sorting attachments problem as well as get rid of backup, license, etc from admin?

Your help is greatly appreciated.

Many thanks.
