I suspect this will be a problem that someone can solve quickly for me, but I've spent hours trying to figure it out without success!
I use FTP Commander to update my website, and have done for years. However, as of yesterday, after overwriting .pdf files on my site in order to update them, I still see the old, outdated version of the .pdf files when I access them through my browsers (Firefox 37.0.1 and IE 11.0.9600.17728). I am running Windows 8.1.
I have tried deleting the browser caches, as well as running CCleaner with all browsers closed and restarting the computer, and the problem persists.
I have tried accessing the .pdf files through another computer (but through the same router) and I still see the old versions, even though FTP Commander shows that those versions no longer exist on the server. I can download the files directly through FTP Commander, and confirm that they are the new version.
If I try browsing to an empty URL on my site then, of course, I find nothing and get a 404 error. If I then upload a .pdf to that URL, then the browsers access it successfully (thus confirming that FTP Commander is functioning). But if I then overwrite that file, the browsers still find the FIRST version that I uploaded, even if I then delete the file altogether. There is no way that I can get back to the 404 error.
Interestingly, I have tried uploading a file to an empty URL, accessing it through Firefox and then deleting it via FTP Commander. If I then try to access this empty URL through Internet Explorer, I *still* see the deleted .pdf, even though I have never accessed it in that browser. So wherever this outdated data is being stored, it doesn't appear to be in the browsers.
Does anyone have any suggestions as to how I can resolve the problem? Might it be that my ISP has started caching for some reason??
