After the upgrade of MediaWiki following the regular upgrade procedure, I receive the following error:

Notice: Use of undefined constant JSON_HEX_TAG - assumed 'JSON_HEX_TAG' in /var/mediawiki-1.22.1/includes/json/FormatJson.php on line 166 Notice: Use of undefined constant JSON_HEX_AMP - assumed 'JSON_HEX_AMP' in /var/mediawiki-1.22.1/includes/json/FormatJson.php on line 166 Fatal error: Call to undefined function json_encode() in /var/mediawiki-1.22.1/includes/json/FormatJson.php on line 167

My PHP version is: 5.5.3-1ubuntu2.1 (apache2handler) My MySQL version is: 5.5.34-0ubuntu0.13.10.1

MediaWiki runs on Ubuntu 13.10

With MediaWiki 1.22 the PHP JSON extension is now required. Maybe it is not istalled/enabled? Look here: Upgrade notices for MediaWiki administrators

Install json and PEAR:

sudo apt-get install php-pear php5-json

Restart apache and it should work.
