<div class="td-instagram-header">
<div class="td-instagram-profile-image"></div>
<div class="td-instagram-meta">
<div class="td-instagram-user">@ExpertVagabond</div>
<div class="td-instagram-followers"><span>153.1k</span> Followers</div>
Follow
<div class="clearfix"></div>
</div>
</div>


so annoying and unprofessional (

thank you for your advice, i managed to change social handles but still can’t find how to remove that annoying “ExpertVagabond” – https://d.pr/i/qAq367

i searched in the database (wp) and this instagram account is mentioned in wp_options table.
lost almost an hour and still no ideas how to remove it 😉

about to choose another theme already ;)))
