Re: tiki "disappears"
Hi derrick,
Unfortunately those error messages don't appear to have anything to do with your Tiki problem.
I have looked at your website and I found something interesting, your list blogs page works (http://yourdomainname/tikifolder/tiki-list_blogs.php) and it appears to have a working "log in" drop down.
It looks like you have not updated your home pages since last August. Did you recently upgrade to Tiki 8.3? Or did you change the menu or any modules recently?
