Can you post a link to your site where you are expecting ads?

The first “Sponsors” heading should have datafeedr ads running. I have put a temporary image widget underneath that, because the ad doesn’t show.
Can you post the shortcode you are using in that widget?
Also, did you check the Enable checkbox for the “Enable shortcodes in Text Widgets” option here: WordPress Admin Area > Settings > Ads?
Yes, the shortcodes are enabled. Here is the shortcode: [dfads params=’groups=-1&orderby=random’]
Can you replace your code with this?
[dfads params="groups=-1&orderby=random"]
That didn’t make any difference. Still not showing.
Can you share with me the code you are using for your ad?
The widget shows this:
[dfads params=”groups=-1&orderby=random”]
The ad looks like this:

Sorry, it changed it to the ad. I was trying to paste the code, but it must be working if it rendered the ad, right?
I don’t really know… if you want to send me login information I can take a look. Send it to help at datafeedr dot com.
After re-saving your “Fat Quarter Shop” ad, it started to work again… Not sure why!
