Attachments are not allowed in the forums due to security reasons. Still, if you need to send us a file you can open a support ticket and attach the file(s) to it. In addition, it will be best if you can open a support ticket and send us a simple running project (incl. CSS, images, skins, DB backup if needed and so on) demonstrating the problem (and step-by-step instructions on doing so). In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.
