Yeap, that was the reason no html was produced. However, we must be bumping on to more than a syntax problem this time.
I have created 2 search forms, each one with a different blog assigned in multisite settings. http://prntscr.com/32qi8p
However, the shortcode is using the first form i created, regardless of the site i am currently using. Is it normal that i can see all forms from all sites' plugin settings?
