well here is some more info :
I installed fireboard on LPC.lu a little time ago and it works fin
here the screenshots of the plugin enabled in fireboard :
gio.net-lux.lu/fire/it_works_shot1.png
gio.net-lux.lu/fire/it_works_shot2.png
---> it is the default configuration of the plugins
you can compare it to the plugins enabled with the recent installation on gio.net-lux.lu (I tried it also on one another site and it did just the same error! ) :
gio.net-lux.lu/fire/it_dont-works-shot1.png
gio.net-lux.lu/fire/it_dont-works-shot2.png
so the problem doesn't seem to be there. So maybe it is as you said : the zip file is corrupted. but I took it from
www.bestofjoomla.com/component/option,co...1/catid,3/Itemid,67/
and I took the STABLE version 1.0.4
euhhh???what can I do else?
