I use the zenppage theme. While trying to enable search within description field (options/search/search behaviour) I am unable to save the setting for decs field - I mark the desc field, set "apply" but this field still remain unchecked.
Is it any "hardcode" way to enable the search within description field with editing any php file?

You are probably not using the latest release. Please update.

I use 1.4.1.1. After upgrade to 1.4.1.2. it works. Thank you!
