I have added Youtube and Twitter details into TrendyMag Options > Social Icon but nothing shows when i reload the site. Just has the ‘Social Counters’ header and nothing. What can i do to troubleshoot ?

UPDATE

So i updated the theme to latest version and it notified me that the “Social Icon Counter” plugin was missing. So i installed the plugin but then the blog doesn’t work.. HTTP 500 on all pages, wp-admin also, until i delete the plugin directory. This is installed on GoDaddy managed WordPress.
