It's obvious that your cron jobs aren't working, and probably won't work the way you have your site presently setup.
When developing I run and test Etano all the time on my computer using a local WAMP server, I don't even have cron jobs setup, I just have to keep regenerating whenever I add new members or blogs, etc., and after regenerating members show up in searches.
When searching make sure you don't have anything pre-selected that might not apply to that member. Try using the basic search without any selections, or try using the search by username field.
If that doesn't work then something is likely wrong with your site or setup besides cron jobs, try looking for clues in the error logs in your Etano Admin.
Etano is capable of running with PHP as a CGI-plugin if your host has it configured properly.
