Hello,
How come I get to see my embedded PDF (using PDF embbeder plugin) in a Unit that I open directly from course page (screenshot), but not when I go through units in Course mode (screenshot)?
Activating or deactivating Wordfence plugin doesn't help.
It did the trick!
However, I do get the notification that there is a attachment when I only want the embedded PDF. What do I do wrong? This is the code used:
[pdf-embedder url="http://metmeestergijs.nl/wp-content/uploads/2018/05/Past-Simple.pdf" title= "Past Simple"]
