[No banners with JS Tag]

Moin moin...

last week i have a perfect working AdServer... but now... i don't know why... Revive shows no more banners...
i don't change something on the Server... i don't touch Revive... Friday i see all banners and yesterday was all gone...

in the meantime i reinstall everything new and update the old DB... but no banner...

on a blank html page i become the error: oa_show is not defined

only the Asynchronous JS Tag and iFrame Tag is working... but with the normal JS Tag i see no banners...

how can i fix this?

 

Best regards
Michael
