I have explained the two ways you ads can not be shown immediately as did Michael earlier in this thread.
You need to check the two things we have stated in this thread before responding back to us saying our support is not to be desired. So is the ad truly paid meaning they are following through the whole process. That is are they paying you in paypal and closing the window or are they clicking the url to come back to classifieds payment script so it can finish the job. If they are not following through the process then the ad will not show. If you have the registered usergroups for example set to moderation then the ads will not show till you approve them.
Is the registered group set to moderation?
Is the user following the payment trail through completion?
Where in admin in what que are the ads when you have to approve them?
