Found the problem. This fix was recommended to move the social media icons in the header from the left side to the right side:
/* Move to right, adjust margin if needed */
.social-block {
float: right;
margin-right: 0px;
}
For whatever reason, I had left this in, even though I had disabled the social icon block. On top of that, I had adjusted the margin-right to -10px. Not really sure what I had planned with that.
