Example Content Search Not Working

After installing the example content and modifying it to suit my needs, I have discovered the search function isn’t working in IE 8 or Firefox 3.6.8. I am not getting any error messages or anything in the log files. Can someone check out my link and see if it works for them?

I’ve read through the wiki and looked over posts on this forum but still don’t see why this isn’t working unless I’ve missed a config setting somewhere although I’ve double checked everything. I never changed a thing with the example content search box in the header other than the location using css or the code in the snippets etc. Oh well, time for some sleep and I’ll try again tomorrow. Hopefully someone will be able to point me in the right direction here.

You get this javascript error when you run a search on your site:

invalid regular expression flag h
[Break on this error] <b>Warning</b>: mb_convert_encoding()...xSearch/classes/ajaxSearchOutput.class

Look at this post, I think this is due to the same bug.
The fix is provided on this post.

Awesome, thanks for the support. I couldn’t get an error message so I had no idea what I was looking for. It is working now.
