I noticed whenever a new user registers to our site, the new user registration email for the admin always appears blank. The information in settings is correct, so data should display. Any idea what might have gone wrong?
We're going to check the issue. I'll update the topic asap.
We don't find such an issue on our test website.
It seems you have an affection on the wpForo function from some plugin. Could you please disable other plugins, then navigate to Email Settings and save those again, then test it again. The activate the plugins one by one and check after each activation to find a problem maker.
