Re: SEFURL & _htaccess file
Normally there is an _htaccess file in TikiWiki's root directory in a fresh installation that is manually renamed to .htaccess . You probably should contact your hosting company to find out if the ))SimpleScripts(( installation put that file there, or if it renamed it, or what. In any event, you can add the file now if you need to, either with FTP or the file manager of your control panel. Post again if you need to, and I can attach the file here.
This is the second recent post about possible strangeness with ))SimpleScripts(( installations. I hope it isn't a trend. 😉
