Hi,

While trying to upload any file in a thread (jpeg, png, pdf) I receive the following error message:

 

This happens even if the file is few KB. The problem started suddently, no new updates or chages were made.

Any ideas?

 

A -200 issue is server side. You would need to check your server error logs to see what is causing this. Generally it will be something like memory_limit or upload_max_filesize that you are hitting
