1click upgrade no loggin in backoffice

[Marvell]

Hi, yesterday I did the prestashop upgrade using the 1 click function on the back office.

 

The process seems to finish without problem.

 

The session on the back office was closed by the upgrade process after upgrade finish and then I could not get access again to it. The shop is not showing a loggin problem, the email / pass I was entering was right.

 

So, I took a look on the server messages and I could see the following lines that correspond with the loggins tries:

I was looking information over inet about the problem and finally I found a solution that works. The solution is disable by database encryption, doing an update in configuration table.

 

The question is that, at the moment, I prefer to know what's the problem and solve it rather than change encryption mode to disable....

 

Can someone help?

 

The initial version was define('_PS_VERSION_', '1.6.0.11'); and the actual (installed) version is define('_PS_VERSION_', '1.6.1.13');

 

The files settings.inc.php and settings.inc.old.php are the same except for the line _PS_VERSION_
