Downgrade 1.5.3

[Arnout]

hi

 

After I upgraded to prestashop 1.6, there where many many problems.

I suppose the theme i bought did'nt support that.

So, i downgraded to 1.5.3. as it was mentioned as the last backup.

After doing that i tried to login in the backend but i get this message

There is 1 error

1. Employee does not exist or password is incorrect.

 

 

Can anyone help me with this issue. I made an backup of database and complete file backup before the upgrade to 1.6

 

template using is the nt544-orange grey

 

Many thanks in advance!
