I setup a slider using pages based on a single category, the slides show up fine in the setup preview but when I add the slider to a content editor page each slide shows up blank. I can still click on them and they go to the right page.
Please check licenses activation and make sure you use latest version of plugins. I’ve just tested it locally and slider loads in the same way as on the preview.
I have the same problem. License is active and valid to next year but posts look fine in the “Content” tab (I want them in the slider) but when I preview the slider is blank but does show the new background colour I chose.
