Hi there,
I updated the plugin to its new version and now the popups do not work when WP Super Cache is enabled (it works perfectly well with it turned off). The popup overlay appears but there is no popup to be seen. Interestingly enough, when you hover over where the popup would be with the inspector turned on it highlights the elements where they should be, but they are invisible and not clickable.
This is a big issue as there are many people that use this very popular caching plugin. Please advise!
