Thread:Project:Support desk/Firefox content encoding error during upgrading tables (MW 1.23.5)/reply (3)

That is basically a change in configuration, which you (in some cases) should/must do in order to keep your system running. We do not file that as bugs normally; it more belongs to the Release Notes of that MediaWiki version for which this change was first needed. I do not know this version right now.

Taking this a step further: It might be an idea to add some code to MediaWiki, which takes care to automatically update outdated configuration options in LocalSettings.php. I know of other systems (e.g. some content management systems), which do exactly that. Anyway, LocalSettings.php does not only have a simple $variable = value; syntax in LocalSettings.php (like many other systems have), but it also has e.g. these if constructs. This will make writing this code way harder. I am currently unsure, if it would be worth the hassle to write something like that...
