System error.
The following error message was returned:
Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'db_europlannet_wiki.tiki_pageviews.day' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
The query was:
SELECT SUM(`pageviews`) AS views, `day` AS unixtime FROM `tiki_pageviews` GROUP BY FROM_UNIXTIME(`day`, '%Y-%m-%d') ORDER BY views DESC LIMIT 1The built query was likely:
SELECT SUM(`pageviews`) AS views, `day` AS unixtime FROM `tiki_pageviews` GROUP BY FROM_UNIXTIME(`day`, '%Y-%m-%d') ORDER BY views DESC LIMIT 1Things to check:
