    at x (jquery.js?ver=1809:5)

I feel it is probably an issue with your theme, try checking the same page using default MyBB theme.

Also can you share your forum url ?

I tried it by the default MyBB theme and didn't get errors.
I don't really want to re-install the theme as i made many edits to it that i don't think i will remember.
