For some time now the search form on my blog hasn't been working, and I can't work out why. If you try to do a search, it thinks for a bit and then comes up with a completely blank page. The searches do appear in the activity log, so the search script is clearly partly working, just not returning a results page.
I upgraded to 4.25 today in the hopes that would fix the problem, and even copied the default search templates over my own, but the problem still occurs.
Everything else is working perfectly. You can see the site at aldenbates.com.
