Can’t see builder “xlwcty_layout_preview”

Hi, recently I changed the url’s from a local project to a server, then install an ssl certificate and I’ve got a lot of problems with the http to https directions, and trying to edit a “thank you” page, It shows the following on console “xlwcty_layout_preview” and another includes js and css files not loading, the plugin works fine at local development, but not on the server, how can I change those urls to https? I assume the problem is that.
