[Mediawiki-l] upgrading to 1.16

[ruud habets]

hi,

I am upgrading to 1.15 (from 1.15.3, skipping 1.15.4) and getting an 
error on a missing l10n_cache table. recreating the table does not solve 
the issue, nor does setting the language to en, prior to updating in 
localsettings.php .

any help is appreciated,.
Ruud
