Uploaded File Names – WordPress is unable to handle file names that contain forward slashes “/” as it interprets the name as a path/URL slug. In other words, if you upload a file that contains forward slashes, any links or embeds of it will not work. This is a common problem for files that have dates in the name in the format of dd/mm/yyyy or any other format that uses forward slashes.

Cache Issues – If you are having difficulty getting to the /wp-admin section of your site, but have accessed it previously and know you should have permission, this may be a browser cache issue. For instructions on clearing your cookies and cache, see the Info Commons Help Desk instructions, here.
