Hey @ed, I’m not the plugin author, but I’m currently hunting a similar problem. I took a look at your site, and I can see that there’s a Javascript error preventing you from getting your feed:
/**/ jQuery112307114415710792243_1464806929804({meta: {error_type: "OAuthAccessTokenException", code: 400,…}})
meta: {error_type: "OAuthAccessTokenException", code: 400,…}
code:400
error_message:"The access_token provided does not match an approved application."
error_type:"OAuthAccessTokenException"
Looks like your access token is invalid – try getting a new one through the “big blue button” at https://www.munamommy.com/wp-admin/admin.php?page=sb-instagram-feed&tab=configure
If this doesn’t work, then you might be in my boat – I updated my token, but it is still set to the old token in the HTML source, and I haven’t figured out why it won’t change.
To see if your token has changed in your HTML, “View source” of your home page and look for this text: (line 1256)
<script type='text/javascript'>
/* <![CDATA[ */
var sb_instagram_js_options = {"sb_instagram_at":"1205343594.97584da.f2687fa9fd8f4c1ea891a28f9544be7b"};
/* ]]> */
</script>
If the token update worked properly, you should see this line change.
