In my wordpress blog, I suddenly got this error on every blog post:
Notice: Undefined index: sfsi_original_counts in /var/www/wp-content/plugins/ultimate-social-media-icons/libs/controllers/sfsiocns_OnPosts.php on line 45
This was due to the ultimaqte-social-media plugin. Hopefully, it could be solved easily by going to the “Ultimate Social Media Icons” link in the left menu. Then, in the page of the plugin, going to the section 6 (“Any other wishes for your main icons?”) and at the bootom of the page, switch the “Error reporting/suppress error message” to yet. Do not forget to presse the “save” button.
Et voilà ! done.
