All file uploads are failing, I can no longer upload any image. I have already tried login out and back in, no luck.
In the past few hours the service appeared to be unstable, I was getting error 503 service unavailable when trying to access wikidot. After that I can no longer upload anything as I get file upload failed.
All my images are just a few Kbs.
[EDIT] I can upload fine now, the error is gone. Was there a problem server side?
