Hello,
I think I have the same problem. I’ve checked the changelog and the reason the slides aren’t appearing is likely due to patch 2.1.19 which adds a feature that hides the slides until the javascript has been executed. However, for some reason the javascript isn’t executing.
– I have no other plugins installed (apart from the default anti-spam plugin)
– I have no javascript errors, warnings or messages in my console.
– I have no failed network requests in my network tab.
– I have tested this on the latest versions of Chrome, Firefox and Safari.
– I am using WordPress version 5.0.1
Is this a known issue? Is there a workaround or fix available?
