I am having the same issue. I have purhased Thrive Themes in order to use Thrive leads (instead of leadpages) and Thrive Architect to have more flexiblity. Unfortunately, when I am trying to use Thrive Architect to build a landingpage, the page doesn’t stop loading and I cannot use the plugin. I have read some support threads here, but have unfortunately not found a solution yet. Could you explain how to proceed?
