Ok, it looks like you’re using a slightly older version of Epik (1.4) The new version is 1.4.1, and you can download that from your account (wherever you purchased it from).
The after-entry widget and css code was added in the latest version. If you have already made adjustments to your css, then I wouldn’t upgrade as it will override your current changes. You can manually add the code to your theme if you need to. Let me know if you’ve added changes or not…..if you haven’t then you should be able to just replace the older version of your theme with the new version.
