I always check that a file has successfully been posted and can open, on several computers, immediately after uploading - so it is there and in working order.
If you are still having problems seeing the new posted file, try the following tips:
- Are you looking in the right place? Is it on the lecture page or the lab page? Check both pages regularly.
- In some cases, a new file will NOT be the last item in the table on the lecture or lab page. Sometimes a new link will appear a few spaces up from the bottom of the table - check the whole table carefully.
- If you have checked that you are on the right page and checked all of the table for the link, hitting the refresh button solves most problems.
- If this still does not work, try clearing the cache.
