Why did my re-uploaded SlideShare not get replaced?
Pranav Bhatnagar September 28, 2010
It can take some time for your new file to be displayed on SlideShare after re-uploading it. You should wait for at least 15 minutes for the changes to take effect. If you still do not see your replacement file after 30 minutes, you may want to clear your browser's cache and try again. This also applies for your SlideShares embedded on external sites.
If you are continuing to see the old file, try opening the presentation URL in a new browser. Sometimes the browser cache causes the old file to appear for a while, even though the replacement was successful.
