[Solved] Upgrade after server migration : blank page

[geraldbigot]

Hello,

Here are the steps I have followed :

1) Install new coreBOS with git : test OK
2) Copy and replace user_privileges and test directories from old to new install
3) Copy old database into new server install :
4) Change dbname, dbuser and dbpass in config.inc.php according to old database

When connecting to CRM URL : first login page : ok
But after user validation : blank page

I activate logs : no FATAL error in vtigercrm.log

Has someone an idea about what's wrong ?

Please help  ;-)
