Question

I recently installed TWiki on RHEL4 and I got everything working as it should. However, I added the calendar plugin and I can't seem to get it working. I added all of the necessary CPAN modules and there aren't any errors on the diagnostics page. I get the following error:

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

missing HTML::CalendarMonthSimple

I checked the logs and can't seem to find anything to help me out. The error seems fairly obvious, but as you can tell, it is causing me a problem. I ran a find and found the following:

[root@localhost ~]# find / -name CalendarMonthSimple* /usr/lib/perl5/vendor_perl/5.8.5/HTML/CalendarMonthSimple.pm /usr/lib/perl5/site_perl/5.8.5/HTML/CalendarMonthSimple.pm~ /usr/lib/perl5/site_perl/5.8.5/HTML/CalendarMonthSimple.pm /usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/HTML/CalendarMonthSimple /root/.cpan/build/HTML-CalendarMonthSimple-1.25/CalendarMonthSimple.pm /root/.cpan/build/HTML-CalendarMonthSimple-1.25/blib/lib/auto/HTML/CalendarMonthSimple /root/.cpan/build/HTML-CalendarMonthSimple-1.25/blib/lib/HTML/CalendarMonthSimple.pm /root/.cpan/build/HTML-CalendarMonthSimple-1.25/blib/arch/auto/HTML/CalendarMonthSimple

Any other ideas would be greatly appreciated.

Check the file permissions of CalendarMonthSimple.pm as well as the directory permissions. Possibly not readable by the web server user?

Based on your comments, the user and group should be set to apache?

-- RobKruciak - 07 Oct 2007

Not necessarily owned by the Apache user, it just needs to be readable. Find out the Apache cgi user by running the configure script.

I ran the configure script and found that apache was the CGI user.

CGI user userid = apache groups = apache,apache

Your CGI scripts are executing as this user.

So, I ran a find and found the following:

[root@localhost ~]# find / -name CalendarMonthSimple.pm /usr/lib/perl5/vendor_perl/5.8.5/HTML/CalendarMonthSimple.pm /usr/lib/perl5/site_perl/5.8.5/HTML/CalendarMonthSimple.pm /root/.cpan/build/HTML-CalendarMonthSimple-1.25/CalendarMonthSimple.pm /root/.cpan/build/HTML-CalendarMonthSimple-1.25/blib/lib/HTML/CalendarMonthSimple.pm

I modified each of these locations so that apache owns all of them. Still no luck. Any ideas?
