I have an issue with the reindex of Magento. I have try to do this with the terminal and this is the response error
Notice: Use of undefined constant MCRYPT_RIJNDAEL_256 - assumed 'MCRYPT_RIJ
NDAEL_256' in /Applications/MAMP/htdocs/Magentooo/vendor/magento/framework/
Encryption/Encryptor.php on line 394
Is there somebody who can help me with this issue?
