Module not working on 1 of 3 sites
Hello, I recently updated to the latest version of the Advanced Search Module along with Common, and the search form on one of my three sites now won't return any results. I enter a search term, click search, the page reloads, but no results appear. I've compared the Advanced Search Form config for this site with the forms that I use on my other sites and can't spot any issues. I've also compared the site-level search settings and didn't see any suspicious differences. This site is using the same theme as one of the other sites (Default Theme v 1.7.2). I also tried removing all of my custom CSS on this site but the search still didn't work. I was previously running Advanced Search module 3.4.6.20 (without Common) and the search form on this site worked with that version.
