Stack overflow at line # when logging in

Hi, I'm hoping you can help me. When logging into our Toastmasters site I get a message noting Stack Overflow at line:6 (sometimes this is line 10), It doesn't appear to be causeing any other issues that I'm aware of at this time, but I'd like to fix it if possible. Can you explain what this is and how I might prevent this message? (please note I'm not very techy )

Brenda

Brenda,

Are you logging in as the admin, or as a member?

Do you know what browser and version you are using?

Hi, the Stack overflow at line # shows when I'm logged in as either a member or the adminitrator, yesterday it was noting line 6 and today it's noting line 10.

our browser is Internet explorer 8, version 8.0.7601.17514

Thank you
Brenda
