We've downloaded & tried to install some contributed modules. Including the Journal and the OU blog. Every time we try and install one of these we get a message saying that it is corrupted or damaged. we then have to remove it before we can get any further (otherwise we get stuck in a loop on the upgrade page). Any ideas on whether the modules are corrupted/broken etc. or is there some other setting in version 2+ that we don't know about? Many thanks.
