Ah, interesting point you’ve made there. Is member press redirecting or just replacing the content with the sign up/login.
I may be wrong in thinking its redirecting, I’ll check the page urls.
If the content is in the default wysiwyg wp editor (the_content) it shows the sign up if not logged in.
If the content is in a acf area, nothing happens, it still shows the content (or a blank page if the code I pasted above is used)
I have asked member press to view this thread and let us know their comments.
