SDT Posted May 17, 2023 Posted May 17, 2023 Sorry, an unknown server error occurred when uploading this file. (Error code: -200)
SeNioR- Posted May 17, 2023 Posted May 17, 2023 (edited) Hi. What file format are you trying to upload? Edited May 17, 2023 by SeNioR-
Marc Posted May 17, 2023 Posted May 17, 2023 Check to ensure its not being blocked by mod_security of similar on your network. A -200 error however is something being returned from your server as being unable to upload
