Mysterious field at registration page?

I recently moved my site from siteground to bluehost successfully, so far.

One thing I did notice is that there appears to be a mysterious blank untitled field on the reg page above "Post/Zip Code".
This page is located here:
https://gelcandlecompany.com/wholesa...ain_page=login

what is this mysterious blank field for? Doesnt seem to interfere with registration.
Thanks for your input.

I can give you part of the answer ...

That field is the state field used in place of the drop down menu when the country is changed to one which doesn't have entries available to populate to the dropdown.

You can see this by changing the country to Canada and then back to USA. The field will then disappear.

If not needed, it should be automatically hidden when the page first loads. That's not happening on your site.

The reason for this is an error during your page load, which means that the javascript to hide the field doesn't get executed properly. Firebug reports this error as "Image corrupt or truncated". Unfortunately it doesn't provide any other information, but with luck that will mean something to you.

I opened my firefox browser and clicked on the firebug icon on the bottom right after I loaded: https://gelcandlecompany.com/wholesa...ain_page=login

I apoligize sounding a little slow but, where can i find that error?
"Image corrupt or truncated".

thank you.

You need to have console enabled for the site and active when you load the page.
