Description Daniel Friesen 2011-09-16 15:29:31 UTC 
I've been getting this error on a test wiki I have the latest 1.18 checked out on. The error shows up when I visit the edit page.

Warning: Invalid argument supplied for foreach() in /languages/Language.php on line 423

Note that this test wiki has CACHE_NONE set since I'm developing. That could be related to the situation where that error shows up.
Comment 1 Sam Reed (reedy) 2011-09-16 15:34:23 UTC 
Might be the same in trunk, at line 460
Comment 2 Daniel Friesen 2011-09-16 15:35:46 UTC 
Perhaps. Though for some reason I only get it in 1.18.
Comment 3 Daniel Friesen 2011-09-16 16:08:31 UTC 
This seams to be related to the LocalizationCache. Running `php maintenance/rebuildLocalisationCache.php --force` does get rid of the error.

The problem though is why was that not when I upgraded the wiki with update.php? If we aren't rebuilding the cache when wikis upgrade we can expect a lot of people complaining in #mediawiki.
Comment 4 Niklas Laxström 2011-09-16 16:28:30 UTC 
I would recommend to make update.php to purge or regenerate the localisation caches.

That's what I just wanted to add to this thread when I saw Niklas had already added it. Niklas, can you add this?

I think you meant r101449; 101499 hasn't been checked in yet. ;)
