Tapastic's image cache is full which basically means you'll be unable to upload any images to the forums until Tapastic decides to fix this problem. A work around solution is to paste the image link, but this will only work on forum posts and not on your profile picture.
Tapastic is aware of this issue and it is on their to do list, but it's not a priority and this problem has been going on for a while now (like 6 months already).
