I’m getting this error now:
“The preview could not load due to the iframe response being incomplete. This is most often related to a plugin conflict, or customizations introducing a PHP error.”
I have two websites working on LearnDash and One was working while the other was not. So that was a goo opportunity to figure out what’s gone wrong.
So I began to update the plugins on the working website one by one and they all worked fine. But as soon as I upgraded from 4.0.10 to 4.1.5 on the pro theme, it broke the site.
So not sure what changed between the two issues, but something between them is causing it.
Where can I download 4.0.10?
