Upload section error 500

In a last two days, upload pictures not work, im recive error 500

Hi, please could you double check the particular JPG file + the data being filled in and submitted?

We seem to be receiving uploads to the screening queue as usually, also FM uploads are arriving. I have also quickly tested two uploads (regular and FM), both were working normally.

If the problem persists, please post a link (external URL) to your JPG file so we can examine it, and also the exact data you are filling into the upload forms, so we can check them too.
