I have recently tried to upload a file through cPanel File Manager and it is stuck at "Starting upload…". It doesn't show any percentage or any sign of starting. The file in question is only a few KB and I have tried uploading other files but they don't upload either.
My maximum file size allowed for upload is 866.72 MB, which should be more than enough.
Why is this happening? I have full root access so I can make any changes if needed.
