How to enable a plugin without GUI?

Continuing the discussion from How to disable a Plugin without GUI?:

I have the opposite problem. One accidental click of the mouse in the plugin manager and I disabled “Common Plugin”. Now all my pages are blank.

I can edit the database, and I see “CommonPlugin” in the record for “plugins_disabled” but I hesitate to edit it.

Is there another way?

In your plugins folder delete the CommonPlugin.php file, and probably all the similar files for other plugins.

Thanks! Okay, that fixes the blank pages. Now I have to reinstall the plugins I had.

Does phplist store the configuration options for plugins somewhere that can be restored after something like this, or do I have to start from scratch?
