Question

Hello. I have asked this question as a follow up to a ticket in which I had an unrelated problem. I hope I am not violating the mores of the forum by posting a second question, but it occured to me that it may not belong in that topic at this point. I am performing a Twiki upgrade from Cairo to Dakar; I'm on the 1 inch line with the ball. Here is the issue: the left sidebar appends itself to the botom of the page rather than displaying in the blank space allocated on the left hand side. I have attached a copy of the image to this page. It does this in the PatternSkin example page itself; In TWikiPreferences I set:
Set SKIN = pattern
and
Set TWIKILAYOUTURL = http://twiki/twiki4.0.2/pub/TWiki/PatternSkin/layout.css
and
Set TWIKISTYLEURL = http://twiki/twiki4.0.2/pub/TWiki/PatternSkin/style.css
It uses the pattern skin color scheme; maybe it's not using the PatternSkin layout? I have also attached the page source from WebHome/main. Thanks!

Answer

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

looks like the CSS files aren't being loaded

• check your access_log (assuming apache) what errors is it reporting?
• check your PubDir setting in configure
• check the permissions on the pub/ directory and below; they should be readable by the web-server

I had the same problem. I think that some of the css was either not copied into the new directory, or was overlayed by the older versions. I ended up doing fresh install, and then manually migrated my data webs into the new install instead of using the upgrade script.

I also believe I've seen some issues with the browser caching the CSS. Shift-Reload on firefox seemed to correct some of my issues.

I had exactly the same issue when doing an upgrade from 4.0.1 to 4.0.2 today. I'm confident that no caching issue was involved, because I traced the HTTP protocol for 304 and 404 situations. Strange enough the variables used in TopBar do not expand according to vartiable definitions - see:

<a href="%WEBLOGOURL%"><img src="%WEBLOGOIMG%" border="0" alt="%WEBLOGOALT%" />

access_log and error_log don't indicate any issue, only the favicon produces a 404 - which should be nothing to complain.

Any idea??! Thanks!

1. Access_log is error free. Error_log reports
[Tue Apr 25 09:32:43 2006] [error] [client 172.16.130.217] [Tue Apr 25 09:32:43 2006] view: Use of uninitialized value in pattern match (m//) at /usr/share/twiki4.0.2/lib/TWiki.pm line 1109. [Tue Apr 25 09:32:44 2006] [error] [client 172.16.130.217] File does not exist: /usr/share/twiki4.0.2/pub/Main/WebHome/web-bg-small.gif, referer: http://twiki/twiki4.0.2/bin/view
2.I looked at the configure script. The paths are correct; The "pub" directory link is broken, however. The pub directory has the correct UNiX permissions:
drwxr-xr-x 26 apache apache 4096 Apr 24 15:35 pub
Here is the Directory block within the Twiki virtual host:
Options FollowSymLinks +Includes AllowOverride None Allow from all
I'm not sure what you mean in the postscript to your message; I set those values in TWikiPreferences. I thought those were where site wide confgurations like SKIN were set. If I click you two linksabove, the Main link does not have a SKIN value set. You seem to be indicating that I shoud set the SKIN and TWIKISTYLEURL etc. values in TWikiPreferences. Am I misunderstanding you?
This error manifests itself whether I perform a manual or a automatic upgrade; in fact, it is [resent in the vanilla installation of TWiki 4.0.2, prior to undertaking any upgrade efforts. I've tried a hard refresh on my browser. Thanks for all your help!

Ok, this ticket can be resolved. LynWood, Soronthar, CDot and Drusilla helped me out in IRC chat. I had to download the new PatternSkin, unzip it, and copy it's files into the correct locations on my new install, in case anyone else has this problem. Just to summarize: in upgrading from Cairo to Dakar, I had to edit Main/TWikiPreferences.txt to include the line <space><space><space>*<space>Set<space>ICONTOPIC <space>=<space>TWiki.TWikiDocGraphics, and I had to download PatternSkin, and copy in the files to their correct locations. Not cookbook, but maybe this advice will help someone out. Thanks all!

Thanks Joseph, regarding the distorted template elements your hint on reinstalling the PatternSkin Plugin helped.

However, one big issue remains:

<a href="%WEBLOGOURL%"><img src="%WEBLOGOIMG%" border="0" alt="%WEBLOGOALT%" />

The TWiki Variables in the TopBar do not get resolved, even though defined in TWikiPreferences and working prior to the 401 to 402 upgrade...

Does anyone have a hint on that!?

Thank you, Dirk
