I had the dev dashboard running on testwp and on vintest. Vintest was a special site for Vinod to do some testing. 2/6 I took it down and deleted all files. I also deleted the dashboard from testwp. Next I have updated coursepress pro to 184.108.40.206 via ftp. It shows in my plugin list as being the current version. Yet I am still getting this update banner. I suspect the way the wpmu dashboard works is why Sucuri site scan yesterday says my testwp site is infected with malware.
