I've made several different versions of this form on 2 different computers, they all come out the same. The previews look very different from what's in FB. The forms are 'smashed' against the far left of the screen. One with a reCaptcha wouldn't display the reCaptcha. The latest one doesn't show the default blue submit button. I can't get any of them to display on the actual website (all files were loaded on server).
Here's how it should look:

Here it is on SDrive:

What the heck is going on?

(Web Form Builder-full, latest version. Both computers are Win7, 64bit)

You didn't upload the CSS file:

I put the form on my SDrive because it didn't look right in the preview, so I wanted to see if it was really messed up, or just the preview.
When I loaded the form on its website and it didn't work, I went to the server and checked the files – compared them to the files for a live form that is working. All were there.
How come this won't preview correctly anymore? And where do I get the CSS file from if it's not included in the upload folders?

This is from the preview – and it links to a 'file not found' message.
I've never had to add a CSS file just to preview a form, it usually just works fine on its own. Anyway, since I've never manually included the CSS (I let FB provide the files for upload), I don't know where to even go looking for this.
Any ideas?

You need to export to get all the files. If you are previewing and copy/paste that will not work.

You should be able to hit publish and it should work on S-Drive.
Maybe close FB and reopen the form and publish again.

Not copy/pasting anything Just clicking preview. The preview is messed up right from FB.
I tried the export > manual set up 4 times, then did the publish to SDrive.
I'm going to try making yet another form and see what happens.

I bet your files for FB are corrupt. I would try reinstalling. It might be the dot net again.

Good idea. Will give it a try.

I grabbed a new FB download, and the preview worked like it should. Looks normal.
I'll do it for my main computer and try the form again tomorrow.
