After update from v5.3 to v5.4, it seems that all the ads have disappeared from the “frontend” and all We get is the text: “<!– Either there are no banners, they are disabled or none qualified for this location! –>”. Everything looks fine in the admin/configuration of the plugin and ads etc. (haven’t been touched prior to the update).
If you’ve updated within 15 minutes of release you you probably downloaded the update so fast that you caught a little bug.
If you re-download the plugin from your account and upload it overwriting the current version you have now it should work again.
