Currently I'm unable to load attachments (screenshots/photos in a jpg format). This has worked for me without problems in the past. A progress bar indicates that the file may have been uploaded but doesn't appear afterwards - and after a "upload" there is a exclamation mark in the (PC) list against the file name
I have around 25/30 past attachments on the forum server and I wonder if I have reached a allocation limit but I can see no way of deleting the previously uploaded files to free space.
