I am using two forms on a single page on a client's WordPress site. A while back I implemented reCAPTCHAs for each form. If I remember correctly you weren't able to use two on a single page so after doing some research I found that it could be done by cloning the first one with javascript.
<div id='ppc-recap'>
...(reCAPTCHA HTML removed for brevity)...
</div>
<div id='ppc-recap2'></div>
jQuery('#ppc-recap2').html(jQuery('#ppc-recap').clone(true,true));
This worked back then however now it is not. I get the following warning in the browser console:
Failed to execute 'write' on 'Document': It isn't possible to write into a document from an asynchronously-loaded external script unless it is explicitly opened.
There are two of these warnings. Each appears to caused by the clones of the two scripts reCAPTCHA uses. I'm lost here, guys.
