If your theme is built on Bootstrap 3, make sure to add the following Custom CSS:
#wbounce-modal-sub.modal {
display: block;
}
I haven’t actually tested it with [captcha], as I am using [quiz], but the [quiz] shortcode starting working once I deleted “id:”. Looks like the the same issue, caused by “id:”
The problem is that the [captcha] shortcode doesn’t support “id:”, which also causes my site to not validate anymore. As my captcha label with “for” attribute can’t be associated with the captcha input.
I ended up deleting for label “for” attribute. But it’s not a good practice, as label “for” is needed for various reasons, like input auto-focus and above all accessibility. I will forward that issue to the plugin author.
For now simply use [captcha] without “id:”
