***Error and solution :***

	**If you get error like following: **

	**“Undefined index: distribution\_name in
	drupal\_install\_profile\_distribution\_name() (line 207 of
	/var/www/html/drupal-7.37/includes/install.inc “**

	**Then run following query in database**

	`***UPDATE*** <http://dev.mysql.com/doc/refman/5.5/en/update.html>`__
	`***system*** <http://localhost/adminer/adminer.php?username=root&db=anuduino_os_hardware_in&table=system>`__
	**`*SET* <http://dev.mysql.com/doc/refman/5.5/en/string-type-overview.html>`__
	status=1 WHERE name='standard';**

	**This will resolve profile error**

	**While going for changing query of theme**

	theme('table', array('header' => $pending\_header, 'rows' =>
	$pending\_rows ));

	solve error of mail sending: email.inc change following line

	change

	**$language-language** replace with **array('language' =>
	$language->language)**

	**$message['body'] = t('…...’);** replace with **$message['body'] =
	array('body' => t('…….));**

	**Error:** *Notice*: Undefined index: distribution\_name in
	*drupal\_install\_profile\_distribution\_name()* (line *207* of
	*/var/www/html/cfd\_fossee\_in\_7/includes/install.inc*).

	FIX this:

	UPDATE \`drupal\`.\`system\` SET \`status\` = '1' WHERE
	\`system\`.\`filename\` = 'profiles/standard/standard.profile';
