Fatal error: Maximum execution time of 120 seconds exceeded in...

To fix it, open your php.ini and replace the value for ‘max_execution_time’ and ‘max_input_time’ as per below.

max_execution_time = 3600
max_input_time = 3600

The biggest problem was, one page checkout page was getting infinite redirection loops. So it was not opening anyhow.

The solution was in Magento Admin only:

System -> Configuration -> Web.
Disable everything under the ‘Session Validation Settings’ box.

<?php

ini_set('max_execution_time', 3600);
ini_set("memory_limit","256M");

$script = "rm -rf var/cache/*";
$results = system($script,$retval);
echo " Cache cleared, RETURN VALUE: $retval\n";

?>

Name the file clearcache.php. Put it in the root directory of the Magento setup & execute in the browser.

If you are using your editor’s built-in search feature, then also it may take lots of time to search within all directories. In case of you are editing the files on the live server, its very awful to search in even small no. of files for code.

However, there is a solution, if your Magento store is hosted on Linux server. You can get advantages of unix commands.

I made a PHP script which can search in the directory. You can set the directory path in which you want to perform the search.

The example script below can search in ‘app’ directory of your Magento setup. Put the script in the root directory.

<?php

ini_set('max_execution_time', 3600);
ini_set("memory_limit","256M");

$item = $_GET['item'];
if(trim($item) != '')
{
	$script = "grep -n -r '$item' ".dirname(__FILE__)."/app";

	// replace 'exe c' with 'exec' in this line
	$results = exe c($script,$retval);
	if($results) {
		echo "Search Done";
		foreach ($retval as $value) {
			echo "".$value;
		}
	}
	else {
		echo "Search Done, No results found.\n";
	}
}
else {
	echo "No Search performed";
}

?>

Name it search.php, then you will need to execute the script from browser this way: http(s)://{host}/search.php?item={keyword}
