Nmidweb2 broke my tree view

[andresrv94]

Hi, i write here because i have a problem. I installed the plugin Nmidweb2 in Cacti 0.8.8b and it broke my tree view. Instead of the drop-down view, i have all the items of my tree already deployed. I tried uninstalling the plugin but the tree keeps the same. I tried copying the files that the plugin hypothetically modifies but remains the same.

I attach a photo of my treeview.
