plugins not appearing in settings

[vmos]

Hello, I upgraded from 0.9.2 to 0.9.5 (ubuntu) and most of my plugins broke, so I yoinked them out and stuck in the newest versions.

I've put them in the plugins directory, named them in main.php, renamed config.in.php.dist, put in the right connecton details and nothing. they're not appearing in the settings, there's nothing in any of the logs, no errors, so I'm slightly stumped. Roundcube is definitely looking for them, when I rename the password folder, it throws up an error.

Can anyone point me in the right direction?

bit of progress, if I stick the old versions back in, they appear again and now the password plugin is working (somehow) still having problems with managesieve filters though.
