Hi,
I have just updated RSForms and a few other components that required updating and I noticed when I update SP Page Builder to version 5.x some non-printable characters appearing as whitespace are showing on the page.
When the "System - SP PageBuilder" plugin is disabled everything works fine. I have contacted RSForms support and they have taken a look and suggested I contact JoomShaper as it looks like your plugin that is breaking it.
Any assistance would be appreciated,
Craig
