My Drupal 7 websites started to throw 500 error when I see the search result page.
How to replicate:
When I enter any keyword and hit search button then I see this URL "http://www.website.com/search/node/keyword" and I see the broken page layout with no result. and I see the error "500 server error" on browser console. Please see the screenshot: https://snag.gy/VsoQqj.jpg
Please see the screenshot of search settings and permissions
