Hi, I got the same problem, I try to put the component to the layout file and i have the {% scripts%} {% styles%} tags in the code. No Popup showing.
I try to delete the plugin and reinstall it No Popup Showing
I got this in the log console : October\Rain\Exception\SystemException: Class name is not registered for the component "launchPopup". Check the component plugin. in /home/thewebsite/www/prod/modules/cms/classes/ComponentManager.php:200
Any clue ?
Thanks in advance for your help.
