It could be that the theme is adding some CSS, have you tried switching to one of the default WP themes to see if it shows up?
But it WAS showing, then I changed some settings, and now it is not. I deactivated and reactivated, but that did not solve the problem either.
Well, I have no idea what you did, but I can recommend going back and figuring it out, maybe by troubleshooting things to see where the affecting change happened. Also, you can try switching to the default theme to see if it’s a theme-related issue.
It was when I enabled Rich Text Editor. When I unchecked it, the form worked. Any ideas why the RTE wouldn’t work?
No idea.. I just tested again and it works fine with RTE enabled.
