Pay with a like won't disappear

Good morning,

I've installed the pay with a like plug-in. After some testing, I wasn't satisfied with the result. So I tried to disable the feature so that the full content should be visible for all pages. But that didn't happen.

After that, I deactivated the plug-in, but still the content is not visible. Now I deleted the plug-in, but my visitors are still confronted with the content block.

Please support so that the content block doesn't show anymore.

Cheers,
Nick Spapens
