ishii,

Maybe there is no version which is not set to "released" state, thus there is no version that should be listed.

I was not able to reproduce your problem with a fresh install of the latest stable 1.3 MantisBT release (1.3.5 at the moment).

If you are running an older version, I recommend that you upgrade to the latest (download from [1]). If after doing so the problem persists, do not hesitate to reopen the issue and provide detailed step-by-step instructions to reproduce the issue; the following additional information may also be useful:

• Exact version of PHP, Database, Web server, Browser and Operating System
• Relevant customizations (e.g. changes in config_inc.php, etc)
• Installed plugins or custom functions ?
• Was the MantisBT source code modified in any way ?

[1] http://mantisbt.org/download.php

Unfortunately, updating to 1.3.5 did not solve the problem. I'm going to collect information you are requesting.
In the mean time, may I ask additional question?

If I add new version to the project managing page, only the version appears in the "target version" menu. Is this an expected behavior?

Here is the detailed info.

I am still missing

detailed step-by-step instructions to reproduce the issue

Did you read/understand what I meant with

Maybe there is no version which is not set to released state, thus there is no version that should be listed.

Versions that are set to released are not listed as target version.

Installed plugins: Meta

I remember there was a plugin with this name a long time ago for MantisBT 1.2.x and early versions of Source plugin.
I would expect that this plugin is not compatible with MantisBT 1.3.x
Check page Manage > Manage Plugins for incomatible plugins.

may I ask additional question?

Please use the forums to get support on customizing and using MantisBT (refer to http://www.mantisbt.org/support.php for links and further details).

ishii,

You did not provide any feedback; I am therefore resolving this issue as "no change required".

Feel free to reopen the issue at a later time and provide the requested information.
