Caching problems with planned posts on multisite

Hey guys,

i’ve got a small multisite installation with a hand full of users and blogs (around 70). I’m using WP Super Cache which basically works fine. Now a few users tried scheduling there posts and seem to have problems with that not beeing published. Partly they just getting not published, but if then it looks like the cache doesn’t get updated so the posts are still only visible when logged in.

Is this a known problem? I’d like to work around that with a real cronjob instead of wp cron as i know from other single site blogs that wp cron is rather unreliable. Unfortunately i haven’t found a solution so far to run a cron job for the whole multisite installation.

Does anyone know of such a thing or of any other solution regarding WP Super Cache?

Thanks,
Helmi
