Hi All,
I uninstall a DNN module that i code. After, i add a new module with same name of old module i uninstalled, there 's a error or bug: in module edit, i don't see tag "module control", and I can't add module into a page.
After check data, I recognize this. When install a module, DNN save information into 2 primary table: ModuleDefinitions and DesktopModules. Desktopmodules contain a path to Desktop Module in DNN folder, and ModuleDefinitions contain foreignkey with DesktopModule.
When i uninstall a module,only information in table DesktopModules deleted, and in talbe ModuleDefinitions still not delete. If i install a new module with a same name as uninstalled module (positon of new module in DNN folder has changed), only infor in DesktopModules create new, and in ModuleDefinitions has old infor. Because, field "FriendlyName" in table ModuleDefinitions is unique key, new infor not create. This matter can make a error as above.

That is error or bug?
