Turkish Local problem

I fixed.

Find in lib/pkp/classes/i18n/PKPLocale.inc.php;

static function initialize($request) {
		self::$request = $request;

		// Use defaults if locale info unspecified.
		$locale = AppLocale::getLocale();
		setlocale(LC_ALL, $locale . '.' . LOCALE_ENCODING, $locale);
		putenv("LC_ALL=$locale");

		AppLocale::registerLocaleFile($locale, "lib/pkp/locale/$locale/common.po");

		// Set site time zone
		// Starting from PHP 5.3.0 PHP will throw an E_WARNING if the default
		// time zone is not set and date/time functions are used
		// http://pl.php.net/manual/en/function.date-default-timezone-set.php
		$timeZone = self::getTimeZone();
		date_default_timezone_set($timeZone);

		if (Config::getVar('general', 'installed')) {
			// Set the time zone for DB
			// Get the offset from UTC
			$now = new DateTime();
			$mins = $now->getOffset() / 60;
			$sgn = ($mins < 0 ? -1 : 1);
			$mins = abs($mins);
			$hrs = floor($mins / 60);
			$mins -= $hrs * 60;
			$offset = sprintf('%+d:%02d', $hrs*$sgn, $mins);

			switch(Config::getVar('database', 'driver')) {
				case 'mysql':
				case 'mysqli':
					Capsule::statement('SET time_zone = \''.$offset.'\'');
					break;
				case 'postgres':
				case 'postgres64':
				case 'postgres7':
				case 'postgres8':
				case 'postgres9':
					Capsule::statement('SET TIME ZONE INTERVAL \''.$offset.'\' HOUR TO MINUTE');
					break;
				default: assert(false);
			}
		}
	}

change with below;

static function initialize($request) {
		self::$request = $request;

		// Use defaults if locale info unspecified.
		$locale = AppLocale::getLocale();
		setlocale(LC_ALL, $locale . '.' . LOCALE_ENCODING, $locale);
		putenv("LC_ALL=$locale");

		AppLocale::registerLocaleFile($locale, "lib/pkp/locale/$locale/common.po");

		// Set site time zone
		// Starting from PHP 5.3.0 PHP will throw an E_WARNING if the default
		// time zone is not set and date/time functions are used
		// http://pl.php.net/manual/en/function.date-default-timezone-set.php
		$timeZone = self::getTimeZone();
		date_default_timezone_set($timeZone);

		if (Config::getVar('general', 'installed')) {
			// Set the time zone for DB
			// Get the offset from UTC
			$now = new DateTime();
			$mins = $now->getOffset() / 60;
			$sgn = ($mins < 0 ? -1 : 1);
			$mins = abs($mins);
			$hrs = floor($mins / 60);
			$mins -= $hrs * 60;
			$offset = sprintf('%+d:%02d', $hrs*$sgn, $mins);

			switch(Config::getVar('database', 'driver')) {
				case 'mysql':
				case 'mysqli':
					Capsule::statement('SET time_zone = \''.$offset.'\'');
					break;
				case 'postgres':
				case 'postgres64':
				case 'postgres7':
				case 'postgres8':
				case 'postgres9':
					Capsule::statement('SET TIME ZONE INTERVAL \''.$offset.'\' HOUR TO MINUTE');
					break;
				default: assert(false);
			}
		}
      
        if ($locale == 'tr_TR') setlocale(LC_CTYPE, 'en_US');
