Question

I have two servers running Debian 3.1 - one without virtual hosts (server A), the other one with (server B, configured through ISPConfig).

There was no problem installing TWiki on server A; but with server B and TWiki is something wrong.

Although I get no error from the configure script, I can't use RcsWrap (RcsLite works). Calling the history of a page leads to the following error:

Content-type: text/plain

TWiki detected an internal error - please check your TWiki logs and webserver logs for more information.

Can't kill STDERR: 'Permission denied'

Datails from the error log:

Since days I can't solve this problem. I compared the configuration of both servers again and again. The only difference I found is that server B uses virtual hosts. Can this lead into these troubles?

Unfortunately I don't understand the error message from the log; so I don't have any idea how to start. Any suggestions what I need to check?

If helpfull I can send the output from the configure script via email.

Answer

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

In the meantime I've setup some virtual hosts on server A and TWiki is still working fine; so this is obviously not the problem. Maybe it's ISPConfig which doesn't like TWiki - I don't know.

Is there anybody who can explain me the error message above. I've no idea what it means? What is TWiki complaining about?

Solution: Permission of dev/null should be crw-rw-rw, but where crw-r--r--. That was the problem with server B.
