Fresh install of plugin and no alteration of config file.

This is what my log is showing: 

[SERVER v1.0.20] Console: VendingManager.cs(92,14): warning CS0114: `Oxide.Plugins.VendingManager.LoadDefaultMessages()' hides inherited member `Oxide.Core.Plugins.Plugin.LoadDefaultMessages()'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword
/home/tcagame/5186/4617/Oxide.Core.dll (Location of the symbol related to previous warning)
VendingManager.cs(234,14): warning CS0114: `Oxide.Plugins.VendingManager.LoadDefaultConfig()' hides inherited member `Oxide.Core.Plugins.Plugin.LoadDefaultConfig()'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword

VendingManager.cs(60,38): warning CS0414: The private field `Oxide.Plugins.VendingManager.oldlocks' is assigned but its value is never used

Any ideas?

None of that log portion is errors, only warnings that are not hurting anything. Check your other oxide/logs file for the actual, full error.

Ok here's the error from the log...
