Installed the testimonials widget yesterday, worked fine. LOVE IT! (see paintingcolumbiamo.com)
Installed again today - different domain but same theme. Am getting a fatal error message, it's near the bottom of columbiamoroofrepair.com -
Fatal error: Call to undefined function has_post_thumbnail() in /home/postcard/public_html/columbiamoroofrepair.com/wp-content/plugins/testimonials-widget/testimonials-widget.php on line 862
By the way, there are supposed to be 3 text boxes at the bottom of that page.
Bought the Premium version of the plugin and activated it - no change, not sure what to try. Thanks!
