Hello to all and thanks for reading.
I have installed and tried the 1.6.1.6 and 1.6.1.7 versions of PrestaShop on localhost (LAMP), everything is fine until I get to the backoffice log in page. Instead of a 'sign in' button, there is just a blue bar, and when I type the user/password, the box disappears and there is only the prestashop logo standing there. Nothing else happens.
I checked with Firebug and I could extract this error:
POST http://localhost/prestashop/admin964qmnwkf/ajax-tab.php?rand=1477297687973
500 Internal Server Error 29ms jquery-....min.js (línia 4)
I also checked the prestashop/log files to find this every time I tried to log in
*ERROR* 2016/10/24 - 10:28:08: Property PrestaShopLogger->message is empty at line 909 in file classes/ObjectModel.php
I have been googling it for several hours and I didn't get anywhere. I would appreciate a lot some sort of help
Thank you in advance!
