The first error would indicate that your oxide/data file is likely corrupt or unreadable.
I am on a server hosted by the company "Nitrado". So I can not do much except to warn them?
You do not have access to your plugin data?
I can. You are proposing to reinstall "oxide"?
No, I am referring deleting the oxide/data file for THIS plugin only; which you can do while the plugin is unloaded. Make sure to back up the file first.
Ok. Thank you for your help @wulf
