You better contact your server administrator/hosting provider for this problem.
I updated some files that people can download from my website on WinSCP and it seemed to go smoothly, however when I visit the site, the downloads dont seem to have updated and I still get the same version of the old file. I disconnected and reconnected in winSCP and the files still show the correct updated version there. I also cleared my chrome cache and still no luck. If anyone can help me that would be much appreciated!
