also i have updated oxide to the latest version and deleted the config data and lang files and reloaded the plugin and nothing seems to get it to work i have tried with only furnace splitter loaded and nothing it just shows those errors and wont split the resources and yes i do have the permission

You have a plugin conflict somewhere with another plugin. To test this remove all plugins and just have Furnace Splitter - should work as intended. From there start loading plugins a couple at a time and you will find the problem plugin that is causing the issue. Troubleshooting 101
