Components not showing on form

Sorry this report was never answered. Webform definitely is capable of adding components in all versions of the module. What you're experiencing is likely caused by a server configuration problem. I'd recommend looking at #585180: Can't add more components, which provided useful insight about similar problems to the one you've described.

I'm experiencing a very similar issue. All other websites on this server (and on others) where I use the webform module work fine.

I created several forms, and added form components. The message text is appearing fine but no form fields are showing. In fact, the only <form> tag appearing in the HTML is the one from the search block. And when I disable the search module there is no form tag at all.

I'm using a subtheme of compositio, which is a subtheme of genesis.

The form may not being showing because you have passed the submission limit. Try removing the submission limit at node/x/webform/configure and see if that makes the elements show up again.

Was unlimited at node/x/webform/configure, turned it into 10 per hour, components still not showing.

The components aren't showing up with Garland either.

It could be an issue related to Display Suite. Going to check that out.

The form components are showing when I dsm them (well, at least in the debug message :)

Yes, when I disable DS the components are showing!

And I found this :) #801216: Webform compatibility
