SMF Sub-account Switch on Portal

Board Software: SMF
Problem With: Sub-accounts (portal page)
Problem: I'm using the sub-accounts mod for SMF 2.0.2 and it works fantastically. That is, until it reaches the portal page (home page). If I try to switch an account from there, a "Not Found" error appears and I press back or go to the forum itself, the account is switched. So the issue is just that when I switch accounts from the portal, it shows the error and I'm not that SMF-savvy (in fact, I'm probably the least now that I've forgotten how to do anything), so I don't know why that is.
Evidence: Here's copy of the message itself:

If you need anything else, I can copy-paste it.

I do! Here's a list of them:

SimplePortal, KeyCAPTCHA for SMF, Auto Refresh Who Index, Member Colour Link, SMF. 2.0.2 Update, Adk Snow Effect, Enhanced PM Popup, Sub Accounts Mod, Tiny Child Boards, BBC Spoiler, Acitivity in Profile, Bookmarks, Anti Bot (Uninstalled), Topic Descriptions

I, personally, would uninstall all your mods and reinstall the subaccounts mod first, do your modifications (if any) and then reinstall the rest of your mods. I had that happen to me, and that's exactly what I did. Uninstalled and reinstalled everything and it worked fine. Or, try the support thread at the SMF community. Here's the support thread. Perhaps someone has had the same issue as you?

Thanks so much

You're welcome! I hated getting it to work, lol.
