The site you linked to does not have WP-Members activated (at least when I looked at it) so not sure I’ll be able to help you.
I had to use a fallback method because I am running a promotion. What can I do to help you troubleshoot? The plugin itself is indeed activated however.
Now the plugin is active, I can see the register button.
Keep in mind when things “disappear” that can be the result of CSS properties. Poorly planned CSS in themes and plugins can inadvertently affect elements outside the intended target. For example, I have seen plugins that implement CSS properties such as “display:none;” applied to a general HTML tag (like input[type=”submit”]) instead of specifying it only to apply to #my-cool-plugin input[type=”submit”].
That’s just one example of many possibilities, so when in doubt, it’s easiest to use the browser inspector to locate an element in the HTML (such as the form’s submit button) and then see what CSS properties are applied and where they are coming from.
Yes I got it working. I was actually mistaking, I am using the WP Simple Membership plugin and noticed there was a separate plugin that was missing (wp-members).
Thanks for at least pointing me in the right direction!
