Moodle in English: Wiki goes to blank page

Wiki goes to blank page

This discussion has been locked because a year has elapsed since the last post. Please start a new discussion topic.

I'm running Moodle 1.4.4+, and have trouble from time to time with Wikis not correctly opening up. When a student in the course tries to go to the Wiki, it just opens up into a blank page with the url http://www.c2.com/cgi/wiki?%20Group%201 or something similar.

The group settings for the course are set to Visible Groups, the students are either in a group called "one" or "two", the Wiki is of type "Groups", and the Wiki is also set to "Visible Groups". I've got what appear to be the same settings on Wikis in other courses, and they work properly.

Any ideas?

Is the URL you displayed any part of your actual site? I don't know why there would be the '/cgi/' part.

This looks like you have a link to some other application in there.

That's the strange part. I have no clue what www.c2.com is. It also bounces to one of these www.c2.com/cgi/ pages if I create a group wiki without having any groups created in the course.

I'm the person who installed moodle here, and I'm the only one with administrator rights, and I've never heard of www.c2.com, and I don't think that we have moodle linking to any other applications.

<Edit>

OK, I just searched through the files in my wiki directory, and I found c2.com referenced in /var/www/html/moodle/mod/wiki/ewiki/ewiki.php. It contains the following:

"WardsWiki" => "http://www.c2.com/cgi/wiki?",
"WikiFind" => "http://c2.com/cgi/wiki?FindPage&value=",

Any idea what these are or what they mean?

Thanks!

I can't help you on your technical difficulties, but c2.com is the site of the first ever wiki, set up by Ward Cunningham in 1995, I believe.

It was, and still is, part of the Portland Repository Project (a software collaboration site, as far as I know) but has grown into a site that is pivotal in the wiki community for discussing practice and new ideas.

When you're on the c2.com page, go to Portland Pattern Repository's Wiki and youll see the wiki.

The only thing I could think is that ewiki is linking to it in an interwiki map way - a lot of wikis link to others for reference.

Sorry I can't help you on the technical front, just a bit of history and speculation.

Hi,
I'm having the same problem.

New Wikis redirect to http://www.c2.com/cgi/ at the end of create process. The Wiki was created, but when I click to get in... again: goes to http://www.c2.com/cgi/.

Older Wikis is still working just fine.

I don't upgrade anything... on moodle.

What could be happening?

Regards, Edu.

Hi mike,

even I solved a similar problem in the german forum. I found the following explanation. In the Wiki code are several words defined as Interwiki-Links. If you name the Wiki with one of this words followed by an ":" it is linked to an other page in the web. Try it with "Wiki:" or "ISBN:". If you don't use such words in the wikiname or no ":" you can use the wiki normaly.
Below are the word I found in the code:

"ErfurtWiki" => "http://erfurtwiki.sourceforge.net/?id=",
           "InterWiki" => "InterWikiSearch",
           "InterWikiSearch" => "http://sunir.org/apps/meta.pl?",
           "Wiki" => "WardsWiki",
           "WardsWiki" => "http://www.c2.com/cgi/wiki?",
           "WikiFind" => "http://c2.com/cgi/wiki?FindPage&value=",
           "WikiPedia" => "http://www.wikipedia.com/wiki.cgi?",
           "MeatBall" => "MeatballWiki",
           "MeatballWiki" => "http://www.usemod.com/cgi-bin/mb.pl?",
           "UseMod"       => "http://www.usemod.com/cgi-bin/wiki.pl?",
           "PhpWiki" => "http://phpwiki.sourceforge.net/phpwiki/index.php3?",
           "LinuxWiki" => "http://linuxwiki.de/",
           "OpenWiki" => "http://openwiki.com/?",
           "Tavi" => "http://andstuff.org/tavi/",
           "TWiki" => "http://twiki.sourceforge.net/cgi-bin/view/",
           "MoinMoin" => "http://www.purl.net/wiki/moin/",
           "Google" => "http://google.com/search?q=",
           "ISBN" => "http://www.amazon.com/exec/obidos/ISBN=",
           "icq" => "http://www.icq.com/",

Any recent update about this? I found that even the most recent 1.6.1+ codes still behave the same way - if you create a new wiki titled (in the Name: field) "wiki:" (without double quotation mark), then it will automatically link to:
http://www.c2.com/cgi/wiki?

I don't think this really make sense, any comments?

Please ignore my previous question. We found the source of this problem. I think it is a special feature of ewiki but it was never documented (as far as I know) in moodle documents. The problematic code is the /mod/wiki/ewiki/ewiki.php and if you comment out the "Wiki" => "WardsWiki", then the problem will be solved. There is this array which has a lot of "InterWiki:Links" which I believe that not necessarily useful for all users:

          "javascript" => "", # this actually protects from javascript: links
           "url" => "",
#          "self" => "this",
           "this" => EWIKI_SCRIPT, # better was absolute _URL to ewiki wrapper
           "jump" => "",
           "ErfurtWiki" => "http://erfurtwiki.sourceforge.net/?id=",
           "InterWiki" => "InterWikiSearch",
           "InterWikiSearch" => "http://sunir.org/apps/meta.pl?",
#          "Wiki" => "WardsWiki",
           "WardsWiki" => "http://www.c2.com/cgi/wiki?",
           "WikiFind" => "http://c2.com/cgi/wiki?FindPage&value=",
           "WikiPedia" => "http://www.wikipedia.com/wiki.cgi?",
           "MeatBall" => "MeatballWiki",
           "MeatballWiki" => "http://www.usemod.com/cgi-bin/mb.pl?",
           "UseMod"       => "http://www.usemod.com/cgi-bin/wiki.pl?",
           "PhpWiki" => "http://phpwiki.sourceforge.net/phpwiki/index.php3?",
           "LinuxWiki" => "http://linuxwiki.de/",
           "OpenWiki" => "http://openwiki.com/?",
           "Tavi" => "http://andstuff.org/tavi/",
           "TWiki" => "http://twiki.sourceforge.net/cgi-bin/view/",
           "MoinMoin" => "http://www.purl.net/wiki/moin/",
           "Google" => "http://google.com/search?q=",
           "ISBN" => "http://www.amazon.com/exec/obidos/ISBN=",
           "icq" => "http://www.icq.com/",

And if you happen to have any of the above showing in the wiki title (e.g., ISBN

, ta-da! then you will have a problem. Just a quick FYI.

I guess the moodle team did not try to clean up the codes when it (Erfurt Wiki) got integrated with Moodle, oh boy..

Thanks, I can't believe this hasn't been fixed till today. Anyway, not the only patched moodle core module here.

Regards,
Raphael
