I'm running MW 1.32, PHP 7.0.33, MySQL 5.6.40 with Vector skin. When is use the built in search, most of the time it works fine. For example, if I search on "Restaurant", I'll get search results and the URL looks like this:
But if I put in a search term where there exists a wiki page with the same name, I get a 404 error. For example, if I search on Automobile, I get a 404 error and the URL looks like this:
I have a wiki page called Automobile:
For some reason, when my search term matches an existing page, my domain name is listed twice in the URL field.
