19688	Using pathinfo permalinks in a subdirectory causes some 404's	mose9634		"Due to circumstances beyond my control, I have a Wordpress site that must be installed to a subfolder named ""s"". I also must use pathinfo type permalinks - thus a page with a slug of store-locator would have the url /s/index.php/store-locator. Unfortunately this results in a 404, but other pages on the site work properly.

I tracked this down, and what I found is that code in class_wp->parse_request is causing this - particularly the code starting around line 166ish in version 3.3. The lines in particular that mess things up are these three:
{{{
$pathinfo = trim($pathinfo, '/');
$pathinfo = preg_replace(""|^$home_path|"", '', $pathinfo);
$pathinfo = trim($pathinfo, '/');
}}}
Coming into these lines of code, $pathinfo is /store-locator/, but after those three lines of code $pathinfo is tore-locator (the leading s is missing). This is because $home_path comes from home_url() which strips trailing slashes. The code right before this block further strips $home_path down to just the subdirectory portion, which in my case is just ""s"". Then the preg_replace fires and the leading s on the path is lost. 

Temporarily, I added the following line before the three lines above and my problems went away:
{{{
$home_path .= ""/"";
}}}
Obviously this only works in my particular situation, and I'd like to be able to run vanilla Wordpress, but I can't find any combination of settings that will preserve my required permalink structure and still work. If there's a configuration combination that I'm missing, I'd be very happy, otherwise, feel free to contact me if you would like more info or if I can help in any way."	defect (bug)	new	normal	Awaiting Review	Permalinks	3.3	normal			mikeschinkel@…
