Backoffice not working after upgrade

[compuman1112]

Hello,

 

After upgrading to Prestashop version 1.6.1.12 the backoffice isn't working. I can't login in backoffice, after filling in the credentials it just refreshes itself and make the field empty again.

Any solotions?

 

Things i tried so far;

• Cleared browser cache
• Cleared history
• Reset username/password
• Different browsers (Chrome, Edge, Firefox)
• Incognito mode within Chrome

 

Please help!

Turn on debbug mode.

Turn on debbug mode.

I did enable it and it tells me this: 

Warning: mcrypt_decrypt(): Received initialization vector of size 7, but size 16 is required for this encryption mode in /mnt/webs/e3/84/54570284/htdocs/Prestashop_01/classes/Rijndael.php on line 68 Warning: Cannot modify header information - headers already sent by (output started at /mnt/webs/e3/84/54570284/htdocs/Prestashop_01/classes/Rijndael.php:68) in /mnt/webs/e3/84/54570284/htdocs/Prestashop_01/classes/Cookie.php on line 343

As soon as i open the backoffice login page it tells me this.

 

Any idea?
