Accidentally deleted /var/www/ - what are my options? #embarrassing

I was in a subdirectory working with some (other) server backups and needed to delete the contents of var/www/ and instead deleted the contents of /var/www/.

Is there any way to restore it short of complete reinstall?

Seems to be working!

Thanks for that. I really didn't want to completely reinstall.

I didn't notice until just now that in the menu sidebar, it only shows default options. So none of the enabled plugins are present in the sidebar.

However, if I view the plugins page, I can see that all of the plugins are still shown as enabled. I can also tell that they are working because. for example, rsnapshot has a daily job that emails me on completion, and I have been receiving that every day, and NUT is allowing login and status updates.

I am a bit concerned about rebooting the machine, as I have the flashmemory plugin enabled, so I'm not clear what issues rebooting the machine may cause, so haven't tried that.

Is there some way to refresh installed plugins? Or update the GUI with all changes that affect it? Something else?

Okay, so it looks like rebooting the machine doesn't change anything and everything seems to be running normally, except that I can't access any of the already enabled plugins because they don't show up in the sidebar.

I tested installing a plugin that I don't use, changing its configuration from default, then uninstalling and reinstalling to see if the configuration was still saved, and the changes are not saved.

Is there anything I can do short of complete reinstall to restore the plugins?
