Hello,
Add the below code to Theme Options > Custom CSS
.mobile-menu-content .et_b_header-socials {
justify-content: flex-start;
}
.mobile-menu-content .et_b_header-socials a:first-child {
margin-left: 0;
}
Go to XStore > Authorization APIs > remove the existing Instagram key and add that again. After that edit the footer Instagram element and read the Instagram user. Save changes and check after that. It looks the existing token just expired.
Regards
