You will need to run Update.php.

The database table l10n_cache is missing n your database. This is the problem.

According to Manual:Database_layout this table should already have been there, when you used MediaWiki 1.21. You might have to add this table manually by looking into the tables.sql file: https://github.com/wikimedia/mediawiki/blob/REL1_29/maintenance/tables.sql#L1533

Update.php (or the web updater by going to mywiki.com/w/mw-config ) will add the table for you, so there is no need to add it manually.

However, this table has been included since MediaWiki 1.16, so unless you are upgrading from pre-1.16, this means that random tables are disappearing from your db. That generally is very bad and you should figure out how that happened.

But isn't update.php using the different patch files, which always contain only a small chunk of the complete table structure? Does it really also add tables, which should already have been there?

It adds tables that should be there provided they were introduced after MediaWiki 1.5 (The update script doesn't know if the table is "missing" or if you are just upgrading from a really really old version of MediaWiki).

So it will work for l10n_cache table. It wouldn't work for say the querycache table

In my case, what should i do?

MediaWiki internal error.
