No results - Global Site Search

Hi there! I've just installed and activated Global Site Search. Everything seems to be allright -Post Indexer up&running, Recent Global Post showing last content- but when I try to search something, I get no data at all (no error message, no content, nothing).

You can try it in the footer of http://www.iwomentv.net.

How could I begin to troubleshoot it?

Thank you very much in advance!

Best,

Jose Miguel
