Question

I'm trying to install the Dakar Release from 06-Nov-2005. This is not my first TWiki install but my first of Dakar. I've followed the steps for configuring apache, then brought up the configure script in a web browser. I set the basic variables that need setting, save, and then I find nothing has been saved. I can't seem to see why it isn't saving the modified settings.

Answer

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.

• First, check the access permissions to LocalSite.cfg and to the lib directory. Both have to be writeable by the user id of the web server, but after an install it's usually you who owns them.
• In Dakar the changes are no longer saved in TWiki.cfg. Instead, there is a separate file LocalSite.cfg in the same directory which holds your local changes.
• If your configure script is running under mod_perl, the configuration might appear unchanged though it has been saved to disk. You might need to restart the web server.

I've checked the items recommended:

• LocalSite.cfg and the lib directory are writeable (I'd run chown -R apache:apache twiki).
• I had used the LocalSite.cfg file rather than changing TWiki.cfg.
• I did have mod_perl loaded. I've now turned that off and restarted the webserver.

One further piece of info. When I load the configure page, there's the following warning up the top of the page:

WARNING:
Error: LocalSite.cfg is unreadable or has a configuration problem that is causing a Perl error - the following message(s) was generated:

I think it's fixed. It seems the solution was to delete the LocalSite.cfg file. I thought I'd tried this earlier but maybe I'd just copied it. Anyway, for Developers who may find it useful, I'm including both the working and broken LocalSite.cfg to look at.

Broken LocalSite.cfg the blank lines were in the file.

# cat LocalSite.cfg.1
$TWiki::cfg{NameFilter} = qr((?-xism:[\s\*?~^\$@%`);
$TWIKI::cfg{WarningsAreErrors} = $TRUE;













$TWiki::cfg{DispScriptUrlPath} = '/twiki/bin';
$TWiki::cfg{Site}{FullLang} = 'en-us';
$TWiki::cfg{PubDir} = '/m/httpd/twiki/pub';
$TWiki::cfg{PubUrlPath} = '/twiki/pub';
$TWiki::cfg{DefaultUrlHost} = 'http://hostname';
$TWiki::cfg{Site}{Lang} = 'en';
$TWiki::cfg{Site}{CharSet} = 'iso-8859-15';
$TWiki::cfg{TemplateDir} = '/m/httpd/twiki/templates';
$TWiki::cfg{Password} = 'XXXXXXXXXXXXX';
$TWiki::cfg{ScriptUrlPath} = '/twiki/bin';
$TWiki::cfg{DataDir} = '/m/httpd/twiki/data';
$TWiki::cfg{LocalesDir} = '/m/httpd/twiki/locale';
1;
# 

The correct LocalSite.cfg :

# cat LocalSite.cfg  
$TWiki::cfg{DispScriptUrlPath} = '/twiki/bin';
$TWiki::cfg{Site}{FullLang} = 'en-us';
$TWiki::cfg{PubDir} = '/m/httpd/twiki/pub';
$TWiki::cfg{PubUrlPath} = '/twiki/pub';
$TWiki::cfg{DefaultUrlHost} = 'http://hostname';
$TWiki::cfg{Site}{Lang} = 'en';
$TWiki::cfg{Site}{CharSet} = 'iso-8859-15';
$TWiki::cfg{TemplateDir} = '/m/httpd/twiki/templates';
$TWiki::cfg{Password} = 'XXXXXXXXXXXXXX';
$TWiki::cfg{ScriptUrlPath} = '/twiki/bin';
$TWiki::cfg{DataDir} = '/m/httpd/twiki/data';
$TWiki::cfg{LocalesDir} = '/m/httpd/twiki/locale';
1;

In Summary: If you're having problems, try deleting LocalSite.cfg and start again.

Ouch. You've been stumbling over an error in bin/configure which has been fixed in SVN some weeks ago.

You have written LocalSite.cfg with a modification in $TWiki::cfg{NameFilter}, and /bin/configure has created a syntactically invalid file. Deleting the bogus line (the first in your broken file) would have been sufficient.
