There is currently not a built in function which allows ads to be posted in multiple categories from the ad posting process (although you can manually do this from the ClassiPress admin). The reason for this is because there are payment settings which are category based, and therefore would be effected by such availability. Making such features available as multiple category posting and featured ads sliders on each category page would require customization of the default theme files on your part. Our themes are not encrypted, so you are free to make changes such as this if you wish.
As you can see from the
ClassiPress demo, if you move the cursor over an image it will show an enlarged preview without the need for clicking the image/ad.
AppThemes does not officially support third party plugins so we cannot guarantee that plugins such as adrotate would be 100% compatible with ClassiPress "out-of-the-box", so to speak. I believe it has been mentioned by customers who have tried it, and additional modifications are required in order for it to function correctly. Thanks.
