If you try to create relative links in the Events Made Easy > Settings > Events tab, to take the user back levels to the original events page, under "Default single event format" in this format:
<a href="../../">Link text goes here</a>
It causes a "Forbidden" error for me. It doesn't when entering it as:
<a href="../">Link text goes here</a>
I know it'd be easier to make the paths absolute, but, when you're developing it's easier to stick with relative.
