Question

I installed Twiki, it kind of worked. I can edit some pages and save. However, I can not register new user. The error message I got on IE6 is:

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

RCS: failed to create file path: Permission denied

In the error.log of Apache, it has this line:

| 22 Mar 2006 - 23:12 | RCS: failed to create file /twiki/data/Main/TWikiUsers.txt: Permission denied at c:/twiki/lib/TWiki/Store/RcsFile.pm line 722.

I checked the code, the "RcsFile.pm line 722" means saving a file.

I checked TWikiUsers.txt, it had 555 privilege and belonged to system. I used "chmod 777 -R *" at /twiki to modify all the files under /twiki (too much? :>)

It worked, I could register one new user without any problem. But, when I tried to register the second new user, I got the same error message as before.

I went to TWikiUsers.txt, it changed to 555 again!.

Who modified it? TWiki program? Why did it not change it back?

Could anybody help me here?

If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list below the edit box.

Make sure all directories and files at and below twiki/data and twiki/pub are owned by the webserver user. The configure script tells you what the webserver user is.

Thanks for your answer. I have all files under /twiki owned by system, which I got from configure: userid. But still have this issue. I just don't understand why the privilege of TWikiUsers.txt changed from 777 to 555 automatically

Actually I used "chown -R system *" at /twiki

Here is what I got in configure:

CGI user userid = system groups = [Cannot identify groups - no Cygwin 'id' or 'sh' command on path]

Sorry, I am not familiar with Cygwin to help debug the groups problem. Hopefully someone else will help.

Thanks anyway. I used "chgrp system -R *" at /twiki. it works now. I am not sure whether it is safe or not, any comment?

I only changed the data directory to my web user to fix this error (chown -R apache data/). I don't think it's a good idea to give the web user permissions to all of the TWiki directories.
