[Upgrade 1.1.1] Problem

[momazia]

Hi everyone

I have a customized 1.1.1 version of Mantis. I do not know which parts of codes are customized.
So I did as below:

1. Download the original 1.1.1 version, Compare each file with 1.1.1 customized version.
2. Apply the same changes to 1.1.7 files. remove Admin folder, and upload the files.
3. Im getting below error:

APPLICATION ERROR #2700
Invalid session handler.
Please use the "Back" button in your web browser to return to the previous page. There you can correct whatever problems were identified in this error or select another action. You can also click an option from the menu bar to go directly to a new section.

I realized the error happens because of the error handler at line 135 of Session_api.php as shown below:

switch( strtolower( $g_session_handler ) ) {
case 'php':
$g_session = new MantisPHPSession( $p_session_id );
break;

case 'adodb':
# Not yet implemented
case 'memcached':
# Not yet implemented
default:
trigger_error( ERROR_SESSION_HANDLER_INVALID, ERROR );
break;
}

Please help me how I can fix it, or is there any other ways to upgrade the version of Mantis for those customized versions or not.

Ur help is really appreciated.

The error occurred because you replaced the file config_defaults.php in the 1.1.1. directory’s for the same file in the 1.1.8. directory.

The files are different, not replace.

Edit it manually.
