I integrated [newsletter] on a page, which worked fine, got the standard subscription box.
Then I changed it to
[newsletter_field name="email" label="Your best email"]
[newsletter_field name="first_name" label="Your name"]
which I just copied from the manual. This text just got displayed on the page, but did not get interpreted. No typos, just copy paste…
Then I wanted to switch back to [newsletter], so I changed it back to what worked in the beginning, but now even [newsletter] is just displayed on the page instead of being interpreted – i.e., no subscription box is shown anymore.
Any ideas how I can fix this?
