MyBB Community Forums

Hello everyone,

I'm currently running a myBB 1.2.6 forum system, and I want to upgrade to the last version of mybb.
I exactly followed upgrade process described at http://wiki.mybboard.net/index.php/Upgrading (downloaded full 1.4.1 package, uploaded all files replacing old ones, and then go to http://www.myforum.com/install/upgrade.php). But the problem is that when I try to access upgrade.php, I simply get a blank page. When I try to check generated HTML source code, it's simply blank too.
What could be the problem ?
I must admit I tried several times to upgrade the forums, by reinstalling the old 1.2.6 version and then restarting upgrade process again and again, but anything seems to work. Upgrade page is always blank...
At first, I believed it was some kind of permission problem, so I tried to CHMOD 777 all forums files, but it didn't change anything.

I would really enjoy your help !

PS: I have no installed plugins nor themes. I simply used the "french+english" install packages (both for the original 1.2.6 and the 1.4.1 I want to install) provided by http://www.mybb.fr website.

Have you tried using the official English 1.4.1 package available on this site?

Hello DennisTT,

Thanks for your answer. I already tried to use the officiel 1.4.1 english package for the upgrade, with the same issue. I just tried one more time again to be sure, and I always got the blank page when browsing to the upgrade.php page

Hello everyone,

I still don't have fixed my problem.
Today, in order to find a solution to it, I decided to modify by myself the upgrade.php page. Thus I changed in the file, the following line

error_reporting(E_ALL & ~E_NOTICE);

by

error_reporting(E_ALL);

then I tried to launch the upgrade script again. I obtained the following error :

Quote:Notice: Undefined index: db_encoding in /home.10.22/tombraida/www/forums/install/upgrade.php on line 34

Notice: Undefined index: pconnect in /home.10.22/tombraida/www/forums/inc/db_mysqli.php on line 187

Notice: Undefined offset: 1 in /home.10.22/tombraida/www/forums/inc/db_mysqli.php on line 197

I checked the config.php file, and I don't have any definition for

$config['db_encoding']

Is it normal ? Is that the problem ?
Thanks a lot for your help, I really want to update to the new version...

Cordly,
