У меня есть сайт под joomla на одном из серверов хостинга. До вчерашнего дня все работало нормально. Но начиная со вчерашнего дня, когда я открываю веб-сайт, я получаю следующую ошибку:
500 - No valid database connection:MySQL server has gone away SQL=SELECT a.*, CASE WHEN CHAR_LENGTH(a.alias) THEN CONCAT_WS(":", a.id, a.alias) ELSE a.id END as slug, CASE WHEN CHAR_LENGTH(cc.alias) THEN CONCAT_WS(":", cc.id, cc.alias) ELSE cc.id END as catslug FROM jos_content AS a INNER JOIN jos_categories AS cc ON cc.id = a.catid INNER JOIN jos_sections AS s ON s.id = a.sectionid WHERE a.state = 1 AND ( a.publish_up = '0000-00-00 00:00:00' OR a.publish_up <= '2012-03-04 17:59:41' ) AND ( a.publish_down = '0000-00-00 00:00:00' OR a.publish_down >= '2012-03-04 17:59:41' ) AND s.id > 0 AND a.access <= 0 AND cc.access <= 0 AND s.access <= 0 AND s.published = 1 AND cc.published = 1 ORDER BY a.created DESC LIMIT 0, 5
Или иногда он просто говорит:
Internal Server Error.
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@mysite.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Что может быть не так с этим? Или проблема в хост-центре?
