I tried to add below plugin in the side bar but doesn’t show. Please help me with this.

Quote of the Day – Site2Quotes

The quotes stopped working and I now get an error whenever I display it:

Fatal error: Cannot use object of type WP_Error as array in /home3/highfive/public_html/wp-content/plugins/quote-of-the-day-site2quotes-widget/site2quotes-widget.php on line 87

Theme: Dyad Version: 1.0.10

It should be very simple according to instructions but nothing shows up..

I added it to the side bar and simply nothing changes.
I removed and changed the order of other widgets to see if that’s the problem but no.
It just doesn’t show.
I’m using Maskitto Light Theme.
Thanks

I love this plugin. Well done!
Is it possible to choose our own background image?

Thanks in advance,
