The Custom Facebook Feed plugin should work in compatibility with most, if not all, caching plugins, but you may need to tweak the settings in order to allow the Facebook feed to update successfully and display your latest posts.  If you are experiencing problems with your feed not updating then try disabling either ‘Page Caching’ or ‘Object Caching’ in W3 Total Cache (or any other similar caching plugin) to see whether that fixes the problem. If you do not wish to disable these options, you can set the Cache Timeout or TTL to something matching your feed update interval, such as 3600 seconds for an hour.
