Error: no such theme PatternSkinTheme after upgrade 1.1.3 -> 1.1.6

I have copied contents of Foswiki-upgrade-1.1.6.tgz on top of existing Foswiki-1.1.3 installation. After that, a line "Error: no such theme PatternSkinTheme" appears in red letters at the top of all pages.

As far as I understand, all PatternSkinTheme files are in place. The Foswiki configuration interface shows no errors.

What's wrong with my installation?

The following new preference setting is required, and overrides the JQuery theme set in configure. Add it to SitePreferences:

   * Set PATTERNSKIN_JQUERY_THEME = PatternSkinTheme

I'm wondering though if something didn't get copied correctly during your upgrade. I've checked the System.DefaultPreferences that we ship in the upgrade package, and it should have had the correct default. Did you save and restore a local copy of that file?

I was going from 1.1.5 to 1.1.6 by using the update package. I copied it including it's directory structure over my existing foswiki folder. I added the above mentioned preference setting in my SitePreferences but still get that red "Error: no such theme PatternSkinTheme" message on top of each page. Any hint what could be wrong with this?

You'll need to go through one save cycle of configure to get register the pattern theme. Or edit the LocalSite.cfg by hand and add

$Foswiki::cfg{JQueryPlugin}{Themes}{PatternSkinTheme}{Url} = '$Foswiki::cfg{PubUrlPath}/$Foswiki::cfg{SystemWebName}/PatternSkinTheme/jquery-ui.css';
$Foswiki::cfg{JQueryPlugin}{Themes}{PatternSkinTheme}{Enabled} = 1;

Alternatively remove the offending lines from the templates using the patch below:

Perfect... the error message is now gone. First I did backout the upgrade to 1.1.6 by restoring a tar I took before and did another attempt to go to 1.1.6 to see if I missed anything, but this ended up with the same error message on each page as before (but luckily fixed another issue I had since I upgraded to 1.1.6). Then I did a closer look to the two parameters you pointed out. They were already set as you mentioned. So did I clean them, saved config, set them back to the original values and saved config again (this forced definitively a "save cycle" with the right values). Now everything is ok. Thanks for your help!

Thank you, the error has gone.

I have added the setting to Main.SitePreferences, and that did not help. Then I went through the configure interface and there reset {JQueryPlugin}{JQueryVersion} to default and enabled {JQueryPlugin}{Themes}{PatternSkinTheme}{Enabled} (I had disabled it when I tried to get rid of the error). That helped.

I have also checked System.DefaultPreferences and the line indeed was there.

I had the same problem. I upgraded Foswiki from 1.1.5 to 1.1.6. One save cycle was enough.

-- KlausReithmaier - 12 Dec 2012

Another way to fix this is to:

   * Set PATTERNSKIN_JQUERY_THEME = foswiki

... which is the default for any other skin. The one coming with PatternSkin seems busted.
