I have flarum installed on a server running ISPConfig. It's installed in a subdirectory of the main domain. (/flarum)
I have setup a subdomain in ISPConfig flarum.mydomain.com and setup a redirect with no flags to /flarum/.
This has worked fine with other things I've installed, kanboard for example, but doesn't seem to work with flarum. If I add the /flarum/ to the end of the url everything seems to work fine.
I suspect that it has to do with the rewrite rules in the .htaccess somehow, but I'm not sure as I don't usually mess with them at all unless it's part of an installation procedure. They usually just work as installed in my experience.
Is there a standard way to get flarum to run in a subfolder, but have the urls not show the full path.
