My install of Twiki (from the December 2000 zip) appears to have trouble extracting the correct webName from the URL - it includes the path to the view script too. I've a feeling I might have made a stupid error, or that it's connected with the $scriptSuffix - due to my hosting, I'm unable to test with out the suffix ".pl".

For example, the web "Main" comes out as "twiki/bin/view.pl/Main". This is then suffixed to $dataDir ("/home/sites/site4/users/andypryke/twiki/data") to give a filepath of "/home/sites/site4/users/andypryke/twiki/data/twiki/bin/view.pl/Main".

Any ideas why?

I've included all the details I could gather below. I'm no perl expert though.

• TWiki version: "Version: 01 Dec 2000"
• Web server: Apache
• Server OS: "Cobalt Linux release 5.0 (Pacifica) Kernel 2.2.14C5 on an i586"
• Perl version: "version 5.005_03 built for i386-linux"

$scriptUrlPath = "/twiki/bin"
$userName = "guest"
webName was"twiki/bin/view.pl/Main" 

(note webName is forced to "Main" just after this output in order that I actually get some web-page appearing).

Answer

I managed to fix this by making the following modification (hack) to the wiki.pm script, I'd still like to know why I needed to do this, so we can give advice or a better fix to other new installers of Twiki.

Because this is a hack and I don't understand the underlying problem, I've left the SupportStatus Category as AskedQuestions.

This should be "/Main/WebHome". Not sure why you get the full path. Is your /twiki/bin set as script executable? In case not I can imagine that you get the full path and not the script path info.

Just encountered the same problem again, this time with the 01-Sep-2001 release. The same hack fixed the problem, though the file to edit is now lib/TWiki.pm

The directory in question isn't script executable, my host uses cgi-wrap instead, and scripts such as "/bin/view" have been renamed "/bin/view.pl"

I've posted a patch that should fix this, over on CobaltRaqInstall - let me know if it works.

Thanks Richard, I'll try it with my next install.
