Go to Appearance / Editor / b-social.php
Then delete this iFrame ...
<iframe src="
https://pro.iconosquare.com/widget/gallery?choice=myfeed&username=<?php echo cz('s_in_name_api'); ?>&hashtag=iconosquare&linking=instagram&show_infos=true&width=323&height=304&mode=grid&pace=10&layout_x=3&layout_y=2&padding=10&photo_border=true&background=FFFFFF&text=777777&widget_border=true&radius=5&border-color=DDDDDD" allowtransparency="true" frameborder="0" scrolling="no" style="border:none; overflow:hidden; width:323px; height:304px;"></iframe>
... and replace it with the shortcode of your desired widget. (Must be a widget that has shortcodes if using Alidropship themes)
But keep in mind ... this will be over-written with each theme update so keep a copy of the modified file. (Unless you're using a Child Theme)
If the widget spills over and is too wide ... try replacing the iFrame above with this....
<div style='width:318px;overflow:hidden;'>
WIDGET SHORTCODE HERE
</div>
I haven't actually done this ... but it should work. Just make a backup of the file first and try it. Maybe adjust the "width:318px" to a higher or lower number
