Unknown error

[jeano0o]

Hello,

I changed the _PS_MODE_DEV_ value from "false" to "true" in defines.inc.php.
I noticed that my site was full of errors.
And that's when I realised why I couldn't update my site, which is currently in version 1.6.1.24.
 Public part error

Warning: Use of undefined constant MCRYPT_RIJNDAEL_128 - assumed 'MCRYPT_RIJNDAEL_128' (this will throw an Error in a future version of PHP) in /home/u539407418/domains/mon-domaine.com/public_html/classes/Rijndael.php on line 124

Can you tell me where the problem is, and how to fix it?

Thank you in advance

Your main problem is that you are using PS 1.6.24 with a PHP version higher than 7.1.

Thank you very much for your help
I have changed the version of php to 7.1
and the error in the public part no longer appears.
However, in the back office
I still have the following error
