Cscope Issue: duplicate cscope database not added

Today I got the error message below when I wanted to use cscope with vim.

Error detected while processing /home/yl/.vim/plugin/cscope_maps.vim:
line   42:
E568: duplicate cscope database not added
Press ENTER or type command to continue


Then finally find the working solution here

To fix this issue, you will need to simply edit the file "~/.vim/plugin/cscopemenu.vim" (or whatever your plugin is named) and edit the line :
set cscopeverbose
to
set nocscopeverbose 
You can also do the same by doing this by adding this line "set nocscopeverbose " to your ~/.vimrc file as well.
