Description
I have recently set up my first multisite with Bedrock, and I have encountered several issues where the URLs are not correct. After some investigation, I figured that the issues are a result of a problem in WordPress Core - in some places it does not honor the site URL setting. This is no problem with a regular WP install, but when WordPress is installed in a subdirectory as it is in Bedrock, the site URL is different from the home URL.
The most significant problem is that some areas in the network admin will direct me to /wp-admin instead of /wp/wp-admin, for example when you're on the My Sites section and click on "Edit Site".
To be clear, this is not a Bedrock bug, but I think it would be great if Bedrock provided a fix for it, so that other people do not run into this problem. While there are ways to workaround this with nginx / htaccess rewrites, I'd prefer to actually fix it from the code site. As of now, I have fixed these issues on my site, so I'll create a pull-request with my approach.
Btw I also created a ticket on Core Trac, the first responses told me that WP doesn't officially support this - so not sure whether there will be a Core fix soon.
