I upgraded from 1.0 (which worked fine) and now when I click Console I get this-
Error php executable is missing from your configuration. Please update NewsSync Settings.
If you have shell access to your account, type "which php" or "where php" and this will tell you the path to enter on the third field of the settings page. If you can't do this, you probably need to ask your ISP.
In my case, PHP was installed as an apache module only, the command-line interface (CLI) was not installed. That was the default installation prior to PHP version 4.3 (December 2002), but version 4.3 and up include the CLI by default. My provider had to update the version of PHP on the server before I was able to use newssync. My path to the executable turned out to be "/opt/bin/php".
Oh, wait, now that I read your post again, I don't think that was really your question!
Regarding the jumble of code when you try to view your settings, I don't think I have any advice other than to try re-installing. Also try to see if you can edit the file /admin/admin_newssync_config.php using a text editor to see if it is corrupted.
