SID-02347: Create new topic is not correctly redirecting.

Status:	Asked	TWiki version:	6.0.2	Perl version:	5.20
Category:	CategoryTemplates	Server OS:	gentoo	Last update:	7 years ago

On my production instance, WebCreateNewTopic redirects to view/ instead of edit/ AND this on a seperate web.

I cannot fix this. I have no idea when it started, or how to revert this behavior. We have live with this for so long, that there is no backup which may contain working files.

Here the behavior in PROD

This will redirect to:

https://wiki.example.com/twiki/bin/view/NewWeb/WebCreateNewTopic?topicparent=WebHome

This https://wiki.example.com/twiki/bin/view/FirstWeb/?onlynewtopic=on&nowysiwyg=0&topic=MyShinyNewTopic&topicparent=WebHome&templatetopic=

On a TEST machine I see the error, and with URL hacking I can see it works the same on PROD

http://wiki-test.example.com/twiki/bin/view/Sandbox/WebCreateNewTopic?topicparent=WebHome

Redirects to http://wiki-test.example.com/twiki/bin/edit/Sandbox/?onlynewtopic=on&nowysiwyg=0&topic=MyShinyNewTopic&topicparent=WebHome&templatetopic=

Any ideas?

Discussion and Answer

It depends on whether and what customizing has been applied to your TWiki in the past... maybe even in an older version if TWiki? The default behaviour of TWiki 6 is defined by the topic TWiki.WebCreateNewTopicTemplate (on twiki.org: WebCreateNewTopicTemplate), but this behaviour can be overridden in quite a few places. The whole story is documented in TWikiTemplates, section "Finding Templates".

The topic you should investigate first is TWiki.WebCreateNewTopicTemplate, or whether you have a topic with the same name in your NewWeb web, or topics ending in SkinWebCreateNewTopicTemplate. Check whether the file has a revision history in your TWiki, and compare it with one directly from the download.

Another location to check is your templates directory: look for a file WebTopicCreate.tmpl or WebTopicCreate.*.tmpl.

If that still doesn't provide a clue, the configuration setting {TemplatePath} (an "EXPERT" setting under "Miscellaneous settings"): It has a list of directories (beginning with absolute paths) and topics (beginning with $web). Compare that to the list in TWikiTemplates, check whether there are "unwanted" entries in this list.

Oh, and there's also the very remote chance that there's a web server redirection in place (but who would implement such a strange thing?).

I diff'd both systems, broken left and working right https://d.pr/i/IHaYGO and it seems they have the same files. I will have to dig further, but still am soooo lost where this could be going wrong.

Hi Harald, there is a redirect in place.

It redirects /$ to a sepcifc web.

The reason is they want to have a specific web as starting web. Can you help there?

This single redirection (which I assume to be some RedirectMatch directive in Apache's configuration) might be a clue, but I can't figure out how this can lead to the symptoms you are observing. We're now leaving TWiki space and entering the Apache and HTTP zone. Here are some ideas to collect diagnostic information:

• Apache's access log should have entries for the redirections. You can fiddle with the LogLevel directive of Apache to get more information.
• Instead of using a browser, you can use the HEAD command (which comes with libwww-perl) to check which URLs are redirected and which aren't. Check the result of HEAD https://wiki.example.com/twiki/bin/edit/NewWeb/.
