I really am baffled... Each time I want to use WPMU DEV Dashboard plugin it is the same problem: none of your recommendations does make it work properly. ALWAYS do I have to write and ask you to help in getting the instant installing of plugins or themes.
Only God Knows why you have it so. However, it is still possible that i am unlucky with this or I always make the same mistake. I don't know, but will you, please, help in getting the plugin working properly?
