site slower after upgrade 60 3.3

I am totally an amateur with WP but after installing this widget, my website is slower too. I’m using the 3.5.1 version.

I’m also getting this error now right underneath my icons (which happen to work). I don’t understand it. The error showed up the next day after installation.

Notice: Undefined offset: 70 in /var/www/vhosts/shelbyalexandergriggs.com/httpdocs/wp-content/plugins/social-media-widget/social-widget.php on line 539

Both problems are happening to me as well.

Sometimes the site will load quickly, other times it takes several seconds for everything to load. (Glad that I am testing it on a dev server.)

I have the same problem had to revert to an older version because the site was very very slow after updating today.
This is happening since version 3.

It was a fine plugin but now….
