Open your index.php file from crm root directory and Add this code
function replace_string_in_a_file($filepath, $search, $replace) {
if (#file_exists($filepath)) {
$file = file($filepath);
foreach ($file as $index => $string) {
if (strpos($string, $search) !== FALSE)
$file[$index] = "$replace\n";
}
$content = implode($file);
return $content;
}else {
return NULL;
}
}
$filepath = $root_directory . 'log4php.properties';
$search = 'log4php.appender.A1.File=';
$replace = 'log4php.appender.A1.File=' . DOMAIN_PATH . '/logs/vtigercrm.log';
$log_properties_content = replace_string_in_a_file($filepath, $search, $replace);
if (!empty($log_properties_content)) {
file_put_contents($filepath, $log_properties_content);
}
