As you can see here the page layout gets destroyed. Below it is an error message generated on the page:
When I disable the plugin "EasySocial for Kunena", suddenly the page works just fine. Upon further investigation the option that breaks the layout is "Enable EasySocial Profiles". Technically I can get the avatars to work without breaking the page, but I cannot have them link to the ES profile without breaking the page layout. Perhaps there is a syntax error going on with the ES Kunena plugin? I'm being very careful with my usage of enabled plugins.
