PrestaShop 1.5.5.0 - Nemôžem sa prihlásiť do administrácie

Hi guys,

TECHNICAL ERROR: Details: Error thrown: [object Object]

My Prestashop version is 1.5.5.0 and I still can not log in to BO.

I have been facing this issue for a few weeks.


I have tried:

1) to use dev mode - no error is being shown

2) to rename gamification folder - did not work

3) to clean cache folder - did not work



Can anybody help me with it?

Thanks.
