Today I just faced an issue while updating some of my articles on WordPress, I was having an error which was (“Update Failed”) whenever I tried to update an article or post. I have also faced issues with the wp multiple content uploader as well. So as expected, after digging through I found out the issue was actually not with WP but with my Web Server. Yeah, My freaking Web Server. It was NGIX+Apache, then I rebuild my server with only Apache and it just working fine. So looks like I might have to configure my NGIX server more If I wanted to use it. Although I really don’t have any issues with the Web Server as long as it works.. Right???
