Whenever i upload a PDF file in my wordpress site, i am getting below error message
“Unexpected response from the server. The file may have been uploaded successfully. Check in the Media Library or reload the page”
But this issue in only intermittent, after some time i can able to upload the file.
I tried without cloudflare DNS, there i could not find any issues.
Could someone give the solution how to overcome the issue, this is very frustrating
