I've setup Forms Based Authentication on my Sharepoint site using various online tutorials. It has both FBA and Windows Authentication and everything works as expected apart from the 'Site Settings' page. When I click to it, it shows me a nice error:
Error
An unexpected error has occurred.

Originally the site was just Windows auth, but I add FBA to it.
When I say Site settings page, I mean just the page that is linked to from the menu (/_layouts/settings.aspx). I can still get to pages that this page provides links to. So for example, I can still get to the 'Title, Description, and Icon' settings page by typing in the url directly (/_layouts/prjsetng.aspx).
Originally, I didn't notice this, but noticed that I could no longer open the site in SharePoint Designer. Because of this I read that I could extend the site, which is just set as windows authentication, and that did indeed allow me to open the site in designer.
This also allows me to open the Site settings page using the new url, so to clarify: http://admin-pc:16132/_layouts/settings.aspx (Original site, FBA and Windows, settings page doesn't work) http://admin-pc:48028/_layouts/settings.aspx (extended site, windows only)
My FBA login I use is just a standard user, so it doesn't have access to the site settings page, I use the windows login to do all site administration stuff.
Essentially, I'd like to know whats going on, and if it's actually possible to do everything on one URL.
Hope someone can help, Thanks in advance!
