My IT guys cloned a site and got the same error. We were unable to correct the problem.
I’m not a web designer or programmer so my terminology might be incorrect, but we finally wiped the site clean, which deleted the database, we started over from scratch with a new WordPress install and now Kiwi is working properly.
We were nervous that the cloning process had caused a database issue, which we did not want to appear several months later in various other plugins.
Bottom line, it took some time, but now Kiwi Logo Slider working as it did before the clone.
Yeah, a real pain.
