A problem was reported to me through my installation at http://www.evangelismtools.org/bible2.php.
I tested it and confirmed a problem. I tested it on your site phpbible.org and the problem exists there too so I though I should definately report it. I will be looking on my installation to try to find the problem.
The whole book of Galations is unavailable to search by book+chapter(+verse).
Try the following search and you will see the issue: Galations 1
