It has just happen that when I try to upload any graphical png formated file after few second of uploading the process being interrupted and says is not a valid png file why I can't figure it out?
same thing on jpg and png for me
By moving the thread the problem is not going to be solved, so far two people are confirming the uploading function for attaching the images is not working and neither administrator nor Moderators have given any response.
They work for me
Today we had some problems with the forum server, that caused this problem. But they should be fixed now and attaching images should work again.
