What about the Front Office. Is it working?

[jusbv]

Front-office works perfectly in dev mode true,

 

the blank page address is

adminxxxxx/index.php?controller=AdminDashboard&token=....

 

i quickly look into the AdminDashboardController.php but there is not exit

 

my login.php page contains only

header('Location: index.php?controller=AdminLogin');

 

thank you

have you tried to turn on error reporting?

then instead white page you should see details about the problem

[jusbv]

dev mode is true in defines.inc.php

 

there is no error in log , in the front office , in login.php or in my blank page

everything seems to be ok but login into back-office stop after connection

 

i tried another administrator, it does same

 

i tried clear cookies, cache on firefox

 

on chrome i had error 500 but not the prestashop 500 error

Now chrome says blank page too

 

it's strange there is no error, i can't debug anything

i remove and reinstall php5-common and his dependance

 

apache access log file says 200 on my request

apache error log file says nothing when i reload my blank Dashboard

 

thank you, sorry for my english, i am french

I solved my problems,

i reinstall the version corredpond to the database,

install broken db with a localhost,

export all table exept configuration, shop_url and all theme table from localhost to internet

 

my Back Office works, front-office too,

my modules updates works too

 

thank you
