have you checked your ow_plugin table to see what the active value is for the plugin in question?
have you reactived all your plugins after update?
this may be a job for the ross man to look at your setup?
This is a first for me guys never had this happen before...
As to the plugin not found, can you please enabled debug mode and try to update plugins again.
If the error persists, can you please check your error logs, is there any error related to the time you tried to update the plugin, if there's, please copy it here
If there's no any, please PM me your admin access details, FTP access details or CPanel.
