WordPress multisite : 3.2.1 with 5 site configured.
Plugin contact form : 2.4.6
well. something very odd had happen here. i have installed the plugin, then i network-activated it, and i put the code in a page. Then, everything work perfectly and i was very happy. But suddenly, the plugin has disappeared in the Dashboard so now, i can't use it in the other site !?
an idea ?
