I'd like to completely remove the following item from my site.

ℋunni, Add that to your css & see if thats what you wanted.

Code:

.popmenubutton {
    display: none !important;
}

That's exactly what I wanted! Thank you so much~ <3.

EDIT: Although it's taken it off, it seems that now the Memberlist can't be read correctly. What way can I keep the item off of my site but still have at least a username in the Memberlist?

You're wonderful! Thank you so much <3.

Solved <3.
