While installing Joomla on OpenShift message was shown that

"PHP mcrypt should be installed or some features of Joomla might not work properly".

Now the Joomla sample website opens sometimes and sometimes doesn't but shows the message:

"Application is not available. The application is currently not serving requests at this endpoint. It may not have been started or is still starting.".

Is it due to PHP mcrypt. I also tried using PHP 5.5 and 5.6. How can I solve this problem and install PHP mcrypt? Also the Joomla setup wizard was not rendering properly. But I installed it anyways.

  • see the details for installation of [mcrypt](http://php.net/manual/en/mcrypt.installation.php) – TIGER Nov 24 '16 at 06:54
  • mcrypt will be removed in PHP 7.1, you should think about migrating to something else. – Xorifelse Nov 24 '16 at 07:00
  • @Tiger But how can I install mcrypt in OpenShift? As I cannot have sudo previliges in the terminal in it's pod. – Jyot Prakash Verma Nov 24 '16 at 14:05
  • It is best not to use mcrypt, it has been abandonware for nearly a decade now. It has therefore been deprecated and will be removed from the core and into PECL in PHP 7.2. It does not support standard PKCS#7 (née PKCS#5) padding, only non-standard null padding that can't even be used with binary data. mcrypt has many outstanding [bugs](https://sourceforge.net/p/mcrypt/bugs/) dating back to 2003. Instead consider using [defuse](https://github.com/defuse/php-encryption) or [RNCryptor](https://github.com/RNCryptor), they provide a complete solution, are being maintained and is correct. – zaph Nov 29 '16 at 21:04
