Greetings to everyone.
After restoring the website backup (OJS 3.3.0.13),
I encountered an issue with uploading files anywhere.
It throws the error: “File could not be uploaded because of a server configuration error. Please contact the system administrator.”
At the same time, the error logs are empty.
In the browser’s F12 menu, I see: Failed to load resource: the server responded with a status of 400 (). journal linck*api/v1/submissions/824/files (when try add submissions file)
Could you please advise in which direction to look to resolve the issue?
I’d be grateful for any suggestions or guidance.
