Odd redirect from custom pages using subdomain

Site is 3653170.toastmastersclubs.org/ (using btoasty as subdomain) - clicking most menu items seems to work, UNTIL you click away from one of two custom pages (Club Officers, Club Photos), then instead of staying on btoasty.toastmastersclubs.org it redirects over here, to www.toastmastersclubs.org/welcome/?N2wl

A similar error (as shown in the attachment) appears sometimes when trying to log in. It appears (this morning) as if there are two completely separate logins (see second attachment with the side by side browser windows).

Can you help us untangle this?

btoasty.toastmastersclubs.org/Club_Officers.html works fine for me

btoasty.toastmastersclubs.org/Photo_Gallery.html works fine for me.

Clear your browser cache.

No, that's not the issue. Go to those pages. THEN, click on Home.

I have cleared cache and cookies. I am NOT the only one experiencing this issue. And I believe the club admin has reported this before, but said you weren't able to replicate it. I'm telling you how to replicate it, and if you look at the attached screenshots, you'll see there's an error message.

[Edited to update: that may not work, either. START from the root: btoasty.toastmastersclubs.org/ then click each menu on the left. After you click Club Officers, click Home. That should reliably replicate the error. I did not get it when STARTING from those pages, either.]

who ever created those pages added this to the page source

remove and it will work

That did the trick! Thank you so much!
