00797: UTF-8 links may break after 2.1.18 upgrade
Description: 2.1.18 seems to be more picky than earlier versions about the order of configuration statements in local/config.php. After doing the upgrade from 2.1.x our links containing UTF-8 "special" characters (äöå) were broken.
I fixed the issue by moving up the include_once('scripts/xlpage-utf-8.php'); statement in the config file. The culprit might have been the membership.php page from the cookbook. It was include_once'd a few rows above xlpage-utf-8.php.
If the UTF-8 script is to be used, then yes, it needs to be loaded before any other recipes.
The UTF-8 page doesn't mention that, however, so this seems easy to miss. Specially when 2.1.12 (probably) and 2.1.18 differ in their interpretation of the config.php file.
The order of includes is important for UTF-8 wikis: see Cookbook:UTF-8 for tips. --Petko September 25, 2007, at 05:57 PM
