Trouble logging into prestashop admin panel?

Question

PHP

Good afternoon, gentlemen
, I encountered such a problem, yesterday the entrance to the prestashop admin panel stopped working (I enter the login password and when I click enter, the page is simply updated)
(everything is on a dedicated server, no work has been done with the server) when you turn on debug, it writes

Warning: mcrypt_decrypt(): Key of size 33 not supported by this algorithm. Only keys of sizes 16, 24 or 32 supported in /var/www/prestashop/classes/Rijndael.php on line 68

when deleting one character with define('_RIJNDAEL_KEY_' debug writes

Warning: mcrypt_decrypt(): Received initialization vector of size 17, but size 16 is required for this encryption mode in /var/www/prestashop/classes/Rijndael.php on line 68

what can be and where to dig, tell me
