I have been trying to upload images but I keep getting this error. I have tried resetting my cookies/cache and I have ensured that the files are the right extension. (.jpg). I upload files here regularly and this is the first time I have ran into problems. It looks like others may be having issues as well.
Your specific error makes more sense to me because SJ is in the process of doing some 'stuff' around here. Please just give him a bit more time and he'll have everything fixed and ready to go. I apologize for the inconvenience. I know it's annoying. I run into my own annoying issues as well but I know things will be straightened out soon so I just hang in there. I hope you can too.
