Theme (WP?) not respecting social login name

Hi. I’m not sure whether this is an issue with Enfold (using 2.4.5) or with WP (using 3.8), so I thought I’d ask here. First of all, I love the multi-author blog option and have successfully included a user profile plugin and I’m redirecting Enfold’s /author to my own /profile using a 301 redirect in htaccess. Don’t know if this is best practice, but it works as expected.

The problem: I’m using a login form which basically just brings the backend stuff to the frontend, and while Enfold works as expected, there is one glaring exception: Social logins (from Facebook, in this case) don’t work with the multi author blog option because Facebook usernames with periods (dots) in them (e.g., peter.parker) get converted to peter-parker, therefore giving an error that no such user exists when clicking on “about author.”. (Specifically: /author/peter.parker becomes /author/peter-parker.) I have pretty perm links set up, so the Theme/WP automatically includes dashes where there are spaces, but shouldn’t peter.parker be read as exactly that, since there is no space? (If it were WP not allowing dots in usernames, I’d assume dots would be stripped the moment the user registers). Moreover, when clicking on author link in the bbpress forum within the site, peter.parker is correctly peter.parker and therefore goes successfully to the peter.parker profile page at /profile (mentioned earlier). It’s actually not a social login problem, I suppose, since any dot in a username would automatically be converted to a dash. That makes me think it may very well be a theme issue/bug. I’d appreciate any clues.

Thanks!
